Eukaryotic N-Glycosylation Occurs via the Membrane-anchored C-terminal Domain of the Stt3p Subunit of Oligosaccharyltransferase

Chengdong Huang, Rajagopalan Bhaskaran & Smita Mohanty
N-Glycosylation is an essential and highly conserved protein modification. In eukaryotes, it is catalyzed by a multisubunit membrane-associated enzyme, oligosaccharyltransferase (OT). We report the high resolution structure of the C-terminal domain of eukaryotic Stt3p. Unlike its soluble -sheet-rich prokaryotic counterparts, our model reveals that the C-terminal domain of yeast Stt3p is highly helical and has an overall oblate spheroid-shaped structure containing a membrane-embedded region. Anchoring of this protein segment to the endoplasmic reticulum membrane is...

Automatically identifying, counting, and describing wild animals in camera-trap images with deep learning

Mohammad Sadegh Norouzzadeh, Anh Nguyen, Margaret Kosmala, Alexandra Swanson, Meredith S. Palmer, Craig Packer & Jeff Clune
Having accurate, detailed, and up-to-date information about the location and behavior of animals in the wild would improve our ability to study and conserve ecosystems. We investigate the ability to automatically, accurately, and inexpensively collect such data, which could help catalyze the transformation of many fields of ecology, wildlife biology, zoology, conservation biology, and animal behavior into "big data" sciences. Motion-sensor "camera traps" enable collecting wildlife pictures inexpensively, unobtrusively, and frequently. However, extracting information from...

Data for: Ecologically relevant thermal fluctuations enhance offspring fitness: biological and methodological implications for studies of thermal developmental plasticity

Joshua M Hall & Daniel A Warner
Natural thermal environments are notably complex and challenging to mimic in controlled studies. Consequently, our understanding of the ecological relevance and underlying mechanisms of organismal responses to thermal environments is often limited. For example, studies of thermal developmental plasticity have provided key insights into the ecological consequences of temperature variation, but most laboratory studies use treatments that do not reflect natural thermal regimes. While controlling other important factors, we compared the effects of naturally fluctuating...

Interpretation of the photoelectron spectra of superalkali species: Na3O and Na3O-

S Zein, J. V. Ortiz & Joseph Vincent Ortiz
Recently measured photoelectron spectra of the Na3O- anion have been interpreted with the aid of ab initio electron propagator calculations. As in the case of the Li3O-, we propose that the photoionization of ground and excited neutral states, in a sequential two photon absorption mechanism, plays a role in the interpretation of the observed spectrum. The lowest vertical electron detachment energy of Na3O- corresponds to a Dyson orbital that is composed chiefly of diffuse Na...

Geophagy of Yunnan snub-nosed monkeys (Rhinopithecus bieti) at Xiangguqing in the Baimaxueshan Nature Reserve, China

Dayong Li, Baoping Ren, Jie Hu, Qingyu Zhang, Yumin Yang, Cyril C. Grueter, Ali Krzton, Xinming He, Ming Li & Alicia Krzton
Geophagy is common in extant nonhuman primate species, but the exact reasons for it across species remain unclear. Previous diet studies on Yunnan snub-nosed monkeys (Rhinopithecus bieti) were only focused on organic materials (plants and small animals). There are no reports on R. bieti exhibiting geophagy in the field before this study. This study was carried out at Xiangguqing in the Baimaxueshan Nature Reserve from June 2008 to May 2009. We recorded the behavior of...

Mindfulness to Manage Workplace Stress and Microaggressions

Chippewa Thomas, Pambanisha Whaley & Jaena Alabi
Navigating workplace stress and microaggressions—verbal and non-verbal messages that are invalidating or demeaning—can be difficult in any profession, but is especially challenging in service-oriented professions like librarianship. In addition to identifying and naming stressors and microaggressions, various tools can be employed to mitigate the negative effects of these encounters. This session will provide attendees with a framework—mindfulness—that can be used to help process the often-fraught interactions that may take place in our libraries. The webinar...

Genomic responses to selection for tame/aggressive behaviors in the silver fox (Vulpes vulpes)

Xu Wang, Lenore Pipes, Lyudmila N. Trut, Yury Herbeck, Anastasiya V. Vladimirova, Rimma G. Gulevich, Anastasiya V. Kharlamova, Jennifer L. Johnson, Gregory M. Acland, Anna V. Kukekova & Andrew G. Clark
Animal domestication efforts have led to a shared spectrum of striking behavioral and morphological changes. To recapitulate this process, silver foxes have been selectively bred for tame and aggressive behaviors for more than 50 generations at the Institute for Cytology and Genetics in Novosibirsk, Russia. To understand the genetic basis and molecular mechanisms underlying the phenotypic changes, we profiled gene expression levels and coding SNP allele frequencies in two brain tissue specimens from 12 aggressive...

A Remodeled Protein Arginine Methyltransferase 1 (PRMT1) Generates Symmetric Dimethylarginine

Shanying Gui, Symon Gathiaka, Jun Li, Jun Qu, Orlando Acevedo & Joan M. Hevel
Protein arginine methylation is emerging as a significant post-translational modification involved in various cell processes and human diseases. As the major arginine methylation enzyme, protein arginine methyltransferase 1 (PRMT1) strictly generates monomethylarginine and asymmetric dimethylarginine (ADMA), but not symmetric dimethylarginine (SDMA). The two types of dimethylarginines can lead to distinct biological outputs, as highlighted in the PRMT-dependent epigenetic control of transcription. However, it remains unclear how PRMT1 product specificity is regulated. We discovered that a...

The P2Y(2) Nucleotide Receptor Mediates Tissue Factor Expression in Human Coronary Artery Endothelial Cells

Ling Ding, Wanshu Ma, Timothy Littmann, Riley Camp & Jianzhong Shen
The discovery of the role of P2Y12 receptor in platelet aggregation leads to a new anti-thrombotic drug Plavix; however, little is known about non-platelet P2Y receptors in thrombosis. This study tested the hypothesis that endothelial P2Y receptor(s) mediates up-regulation of tissue factor (TF), the initiator of coagulation cascade. Stimulation of human coronary artery endothelial cells (HCAEC) by UTP/ATP increased the mRNA level of TF but not of its counterpart-tissue factor pathway inhibitor, which was accompanied...

Active Site-labeled Prothrombin Inhibits Prothrombinase in Vitro and Thrombosis in Vivo

Heather K. Kroh, Peter Panizzi, Svetlana Tchaikovski, T. Regan Baird, Nancy Wei, Sriram Krishnaswam, Guido Tans, Jan Rosing, Bruce Furie, Barbara C. Furie & Paul E. Bock
Mouse and human prothrombin (ProT) active site specifically labeled with D-Phe-Pro-Arg-CH2Cl (FPR-ProT) inhibited tissue factor-initiated thrombin generation in platelet-rich and platelet-poor mouse and human plasmas. FPR-prethrombin 1 (Pre 1), fragment 1 (F1), fragment 1.2 (F1.2), and FPR-thrombin produced no significant inhibition, demonstrating the requirement for all three ProT domains. Kinetics of inhibition of ProT activation by the inactive ProTS195A mutant were compatible with competitive inhibition as an alternate nonproductive substrate, although FPR-ProT deviated from this...

Subunit D of RNA Polymerase from Methanosarcina acetivorans Contains Two Oxygen-labile [4Fe-4S] Clusters IMPLICATIONS FOR OXIDANT-DEPENDENT REGULATION OF TRANSCRIPTION

Faith H. Lessner, Matthew E. Jennings, Akira Hirata, Eduardus C. Duin & Daniel J. Lessner
Subunit D of multisubunit RNA polymerase from many species of archaea is predicted to bind one to two iron-sulfur (Fe-S) clusters, the function of which is unknown. A survey of encoded subunit D in the genomes of sequenced archaea revealed six distinct groups based on the number of complete or partial [4Fe-4S] cluster motifs within domain 3. Only subunit D from strictly anaerobic archaea, including all members of the Methanosarcinales, are predicted to bind two...

On the accuracy of explicitly correlated coupled-cluster interaction energies - have orbital results been beaten yet?

Konrad Patkowski
The basis set convergence of weak interaction energies for dimers of noble gases helium through krypton is studied for six variants of the explicitly correlated, frozen geminal coupled-cluster singles, doubles, and noniterative triples [CCSD(T)-F12] approach: the CCSD(T)-F12a, CCSD(T)- F12b, and CCSD(T)(F12*) methods with scaled and unscaled triples. These dimers were chosen because CCSD(T) complete-basis-set (CBS) limit benchmarks are available for them to a particularly high precision. The dependence of interaction energies on the auxiliary basis...

Valence and diffuse-bound anions of noble-gas complexes with uracil

Livia Streit, O. Dolgounitcheva, V. G. Zakrzewski, J. V. Ortiz & Joseph Vincent Ortiz
Valence-bound (VB) and diffuse-bound (DB) anions of noble-gas (Ar, Kr, and Xe) complexes with uracil have been studied with ab initio methods. MP2 optimizations revealed minima corresponding to anions of both kinds in each case. Coupled-cluster singles and doubles with perturbative triples, CCSD(T), and electron propagator single-point calculations were performed in order to assess vertical and adiabatic electron detachment energies of these complexes. Ab initio electron propagator calculations employed the outer valence Green’s function and...

Marisha Speights Atkins, Dallin J. Bailey, Cheryl D. Seals, Guorui Li, Robertson Bassy, Yang Cao, Sicheng Li, Abigail Bennett, Chaohui Ren, Chang Ren, Ishaan Mishra, Yaoxuan Luan & Jueting Liu
The Automated Phonetic Transcription Grading Tool (APTgt) is an online Learning Management System (LMS) that facilitates the comparison of phonetic transcriptions for instruction and clinical training purposes. It uses an embedded IPA graphical keyboard for transcription input. A custom edit distance algorithm aligns transcriptions in an intuitive way and then calculates differences quantitatively. This allows for objective scoring of transcriptions of even severely impaired productions, which may be difficult to score via traditional comparison methods....

Experimental and numerical investigation of saltwater intrusion dynamics in flux-controlled groundwater systems

Sun Woo Chang & T. Prabhakar Clement
Sea level rise and reduction of groundwater fluxes due to changes in rainfall patterns are the two major climate change–induced hydrological variables that can severely affect saltwater intrusion in coastal aquifers. In this study we use a combination of laboratory experiments and numerical simulations to study the impacts of changes in one of these climate change–induced hydrological variables, groundwater flux, on saltwater intrusion process. We have completed experiments in a laboratory-scale model to study the...
