Comments
  • FUNCTION: May be an antioxidant enzyme particularly in the developing shoot and photosynthesizing leaf. Involved in the detoxification of alkyl hydroperoxides with reducing equivalents provided through the thioredoxin system (By similarity).
  • CATALYTIC ACTIVITY: 2 R'-SH + ROOH = R'-S-S-R' + H2O + ROH.
  • SUBUNIT: Homodimer; disulfide-linked, upon oxidation (By similarity). Interacts with the plastidial NADPH-dependent thioredoxin reductase NTRC.
  • SUBCELLULAR LOCATION: Plastid, chloroplast (By similarity).
  • PTM: The Cys-114-SH group is the primary site of oxidation by H(2)O(2), and the oxidized Cys-114 (probably Cys-SOH) rapidly reacts with Cys-236-SH of the other subunit to form an intermolecular disulfide. This disulfide might subsequently be reduced by thioredoxin (By similarity).
  • SIMILARITY: Belongs to the ahpC/TSA family.
  • SIMILARITY: Contains 1 thioredoxin domain.
