The aim of this study is to identify, clone and express a Mycobacterium avium subsp. paratuberculosis specific immunogenic antigen candidate, in order to develop better reagents for diagnosis and vaccines for the protection of the host. Therefore, MAP2191 gene (a member of MAPmce5 operon) from MAP, was isolated and characterized by Bioinformatics tools and <e...

If we know the structures of the proteins A and B, and the function of protein A, then if we can detect structural similarity between A and B by producing an alignment between them, it can help us infer functionality of B. The problem of protein structure alignment is essentially similar to the sequence alignment; the fact that we have to do structural alignment in 3-d adds to the complexity of...

Background: The present study has been designed with the aim of evaluating A-kinase anchoring proteins 3 (AKAP3)and Procollagen-Lysine, 2-Oxoglutarate 5-Dioxygenase 3 (PLOD3) gene mutations and prediction of 3D proteinstructure for ligand binding activity in the cases of non-obstructive azoospermic male.Materials and Methods: Clinically diagnosed cases of non-obstructive azoos...

conclusions the comprehensive analysis of a protein with important roles has never been easy, and in case of e2 envelope glycoprotein of hgv, there is no much data on its molecular and immunological features, clinical significance and its pathogenic potential in hepatitis or any other gbv-c related diseases. so, results of the present study may explain some structural, physiological and immunol...

to investigate the interaction and adsorption of drug and carbon nanotube on human serum albumin, three anti-cancer drugs ([pd(phen)(r-gly)]no3, r = methyl, propyl and amyl) with different hydrophobic tails and anticancer activities were selected. these drugs have better anti-tumor activity and less side effects than that known cis-platinum drug. human serum albumin is also important for drug d...

Background & Objective: A main contest in chemotherapy is to obtain regulator above the biodistribution of cytotoxic drugs. The utmost promising strategy comprises of drugs coupled with a tumor-targeting bearer that results in wide cytotoxic activity and particular delivery. The B-subunit of Shiga toxin (STxB) is nontoxic and possesses low immunogenicity that exactly binds to t...

background: sigma factors are proteins that regulate transcription in bacteria. sigma factors can be activated in response to different environmental conditions. the rpos (rna polymerase, sigma s) gene encodes sigma-38 (σ38, or rpos), a 37.8 kda protein in pseudomonas aeruginosa (p. aeruginosa) strains. rpos is a central regulator of the general stress response and operates in both retroactive ...

prpc conversion to prpsc isoform is the main known cause for prion diseases including crutzfeldt-jakob, gerstmann-sträussler-sheinker syndrome and fatal familial insomnia in human. the precise mechanism underling this conversion is yet to be well understood. in the present work,  using the coordinate file of prpc (available on the protein data bank) as a starting structure, separate molecular d...
