2'-hydroxybiphenyl-2-sulfinate desulfinase M-CSA #971 | Part of a bacerial 4S pathway that removes covalently bound sulfur from dibenzothiophene (DBT) without breaking carbon-carbon bonds. This enzymatic system employs four different enzymes (DszA, DszB, DszC, and DszD) to work sequentially in order to oxidize the C−S bond and remove the oxidized sulfur as HSO3-. Bacteria use the oxidized sulfur for their anabolic needs such as producing sulfur-containing amino acids. DszB naturally metabolizes 2′-hydroxybiphenyl-2-sulfinate (HBPS) into biphenyl-2-ol without using cofactors. This reaction might be useful in the future for the processing of crude oil in a more environmentally friendly and lucrative way. | Defined by 5 residues: SER:A-25CYS:A-27HIS:A-60ARG:A-70GLY:A-73 | EC: 3.13.1.3 (PDB Primary Data) |
