[1]	NUCLEOTIDE SEQUENCE [MRNA]. McGonigle S., James E.R.; "1-Cys peroxidoxin from Dirofilaria immitis."; Submitted (SEP-1997) to the EMBL/GenBank/DDBJ databases.

Comments

FUNCTION: Thiol specific antioxidant.
CATALYTIC ACTIVITY: 2 R'-SH + ROOH = R'-S-S-R' + H₂O + ROH.
SUBCELLULAR LOCATION: Cytoplasm (By similarity).
PTM: Cys-49 is the site of oxidation by H(2)O(2). The oxidized intermediate might be Cys-SOH (By similarity).
SIMILARITY: Belongs to the ahpC/TSA family. Rehydrin subfamily.
SIMILARITY: Contains 1 thioredoxin domain.
