Protein attributes

Sequence length446 AA.
Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Catalyzes the four-electron reduction of molecular oxygen to water.

Catalytic activity

NADH + acceptor = NAD+ + reduced acceptor.

Cofactor

Binds 1 FAD per subunit By similarity.

Subunit structure

Homodimer.

Post-translational modification

The N-terminus is blocked.

Miscellaneous

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

Sequence similarities

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