Current Trends in Biotechnology and Pharmacy

Sulfur is amongst the most profuse elements on the globe and a vital component for life maintenance. Sulfite reductase plays a key role in sulfur pathway. It converts sulfite to sulfide. Reductase enzyme is present in sulfur reducing bacteria. Three organisms from Desulfovibrio species namely, D. alaskensis, D. vulgaris, Desulfovibrionaceae are used in this study. The computational analysis has been done out on the sulfite reductase enzyme form the above listed sulfur reducing bacteria using in silico tools. The study focused on mainly structural analysis, structural determination and structural validation as well. Structure of D. vulgaris is present in PDB and it is used as template for analyzing the structures of D.alaskensis and Desulfovibrionaceae using different structural validation and modelling online tools. Among the homology modeling tools used, based on the validation of structures using RAMPAGE tool, Swissmodel server gave the best models upon which the scientific community can be relayed. These modeled structures can be further used in molecular docking and molecular dynamics and simulation studies.
