Bacteriol. 185:2330-2337(2003). CC -!- FUNCTION: Directly reduces alkyl hydroperoxides with the use of CC electrons donated by the 57 kDa flavoprotein alkyl hydroperoxide CC reductase (By similarity). CC -!- CATALYTIC ACTIVITY: 2 R'-SH + ROOH = R'-S-S-R' + H(2)O + ROH. CC -!- SUBUNIT: Homodimer; disulfide-linked, upon oxidation (By CC similarity). CC -!- PTM: The Cys-47-SH group is the primary site of oxidation by CC H(2)O(2), and the oxidized Cys-47 (probably Cys-SOH) rapidly CC reacts with Cys-166-SH of the other subunit to form an CC intermolecular disulfide. This disulfide is subsequently reduced CC by thioredoxin (By similarity). CC -!- SIMILARITY: Belongs to the ahpC/TSA family. CC -!- SIMILARITY: Contains 1 thioredoxin domain.
