Methods and fluid compositions are provided for decreasing an amount of sulfur-containing compounds in downhole fluids and/or subterranean reservoir wellbores by including at least one enzyme destabilizer in a fluid composition. The fluid composition may then be circulated into a subterranean reservoir wellbore. The fluid composition may further include a base fluid and at least one sulfur producing enzyme. The base fluid may be or include, but is not limited to, drilling fluids, servicing fluids, production fluids, completion fluids, injection fluids, refinery fluids, and combinations thereof. The enzyme destabilizer(s) may be destabilize the sulfur producing enzymes and thereby decrease an amount of sulfur-containing compounds produced vis-à-vis the sulfur producing enzyme(s). |

Disclosed is an O-phosphoserine sulfhydrylase (OPSS) mutant which has a Mycobacterium smegmatis-derived amino acid sequence corresponding to that of SEQ ID NO: 1 which is devoid of three to seven C-terminal amino acid residues. Also, a nucleic acid molecule encoding the OPSS mutant, an expression vector carrying the nucleic acid molecule, and a transformant transformed with the expression vector are disclosed. In addition, a method is provided for producing cysteine in which O-phospho-L-serine (OPS) is reacted with a sulfide in the presence of the OPSS mutant. The OPSS mutant has improved enzymatic activity and can be applied to the environmentally friendly production of L-cysteine through a simple enzymatic conversion reaction. |
