Protein existenceEvidence at protein level

General annotation (Comments)

Function

Peroxidase whose active site is a redox-active cysteine-sulfenic acid.

Catalytic activity

NADH + H2O2 = NAD+ + 2 H2O.

Cofactor

Binds 1 FAD per subunit.

Subunit structure

Homotetramer.

Miscellaneous

The active site is the redox-active Cys-42 oxidized to Cys-SOH. The oxidized form is stabilized by an hydrogen bond formation with His-10.

Sequence similarities

Belongs to the class-III pyridine nucleotide-disulfide oxidoreductase family.
