Model of G-alpha-i3 bound to the GIV GBA-motif

The activation of heterotrimeric G proteins is typically achieved by guanine nucleotide exchange factor (GEF) proteins that facilitate the exchange of GDP for GTP on G-alpha subunits. While this exchange activity is typically performed by G protein-coupled receptors (GPCRs), cytosolic non-receptor type GEFs have been more recently described as G-alpha activators. A subset of the described non-receptor GEFs contain a Galpha-Binding and Activating (GBA) motif. This short, evolutionarily conserved motif is known to confer nucleotide...

Bacillus subtilis YolD protein

The YolD family (that includes both Bacillus subtilis YolD (this model) and YqjX) is part of the WYL-like superfamily, predicted to have an SH3 β-barrel fold related to Sm domains. In our analysis, among the closest detected structural matches were E. coli YaeO, a Rho-specific inhibitor of transcription termination, and a cyanobacterial Hfq homolog. Model assessment showed that YqjX and YolD sequences are indeed compatible with the SH3 β-barrel structure. Interestingly, UmuD' has an all...

Arabidopsis DXO1 links RNA turnover and chloroplast function independently of its enzymatic activity

The DXO family of proteins participates in eukaryotic mRNA 5′-end quality control, removal of non-canonical NAD+ cap and maturation of fungal rRNA precursors. In this work, we characterize the Arabidopsis thaliana DXO homolog, DXO1. We demonstrate that the plant-specific modification within the active site negatively affects 5′-end capping surveillance properties of DXO1, but has only a minor impact on its strong deNADding activity. Unexpectedly, catalytic activity does not contribute to striking morphological and molecular aberrations...

An electron transfer competent structural ensemble of membrane-bound cytochrome P450 1A1 and cytochrome P450 oxidoreductase

The aim of this study was to use molecular modelling and simulation to investigate how cytochrome P450 1A1 and its redox partner, cytochrome P450 reductase, form an electron transfer competent complex in a phospholipid bilayer. We used a multiresolution computational approach, combining Brownian dynamics, coarse-grained and all-atom molecular dynamics simulations to model the complex. The structural parameters and electron transfer rates agree well with experimental data.

COMPUTATIONAL MODEL STRUCTURE OF SARS-CoV-2 NON-STRUCTURAL PROTEIN 2 (nsp2)

The structure of 'SARS-CoV-2 NON-STRUCTURAL PROTEIN 2 (nsp2)” is a part of the project “In silico Proteome analysis of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” (Baruah et al., 2020; In communication) based on the sequence analysis and complete coordinate structure prediction of full SARS-CoV-2 proteome based on the NCBI reference sequence NC_045512 (29903 bp ss-RNA) which is identical to GenBank entry MN908947 and MT415321.

COMPUTATIONAL MODEL STRUCTURE OF SARS-CoV-2 ORF3a protein

The structure of 'SARS-CoV-2 ORF3a protein' is a part of the project “In silico Proteome analysis of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” (Baruah et al., 2020; In communication) based on the sequence analysis and complete coordinate structure prediction of full SARS-CoV-2 proteome based on the NCBI reference sequence NC_045512 (29903 bp ss-RNA) which is identical to GenBank entry MN908947 and MT415321.

Defining a novel domain which provides an essential contribution to site-specific interaction of Rep protein with DNA

The essential feature of replication initiation proteins is their ability to bind to DNA. In this work, we describe a new domain that contributes to a replication initiator sequence-specific interaction with DNA. Applying biochemical assays and structure prediction methods coupled with DNA-protein cross-linking, mass spectrometry, and construction and analysis of mutant proteins, we identified that the replication initiator of the broad-host-range plasmid RK2, in addition to two winged helix domains, contains a third DNA binding...
