Abstract

Organophosphate compounds bioremediation by use of organophosphorus degradation enzymes such as DFPase is a developing interest in industry and medicine. The most important problem with the bio-catalytic enzymes is their instability on high temperatures. This work carried out to find suitable locations for introducing disulfide bridges in DFPase enzyme. We employed some computational approaches to design the disulfide bridges and evaluate their roles in the enzyme structural thermostability. According to the in silico results, mutant 6 (V24C, C76) increased the enzyme thermostability relative to wild-type.
