General annotation (Comments)

Function

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

Catalytic activity

NADH + acceptor = NAD(+) + reduced acceptor.

Cofactor

Binds 1 FAD per subunit By similarity.

Miscellaneous

The active site is the redox-active Cys-44 oxidized to Cys-SOH. The oxidized form is stabilized by an hydrogen bond formation with His-11 By similarity.

Sequence similarities

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

Mass spectrometry

Molecular weight is 49603.57 Da from positions 1 - 456. Determined by ESI. Ref.2
