BRITE hierarchy
Sysname
2'-hydroxybiphenyl-2-sulfinate sulfohydrolase
Reaction(IUBMB)
2'-hydroxybiphenyl-2-sulfinate + H2O = 2-hydroxybiphenyl + sulfite [RN:R07311]
Reaction(KEGG)
Substrate
2'-hydroxybiphenyl-2-sulfinate [CPD:C06742];
H2O [CPD:C00001]
Product
2-hydroxybiphenyl [CPD:C02499];
sulfite [CPD:C00094]
Comment
The enzyme from Rhodococcus sp. strain IGTS8 is encoded by the plasmid-encoded dibenzothiophene-desulfurization (dsz) operon. The enzyme has a narrow substrate specificity with biphenyl-2-sulfinate being the only other substrate known to date [2].
