General annotation (Comments)

Function

FAD-dependent sulfhydryl oxidase that catalyzes disulfide bond formation. The complete pathway for formation of disulfide bonds in intracellular virion membrane proteins sequentially involves oxidation of E10, A2.5 and G4 By similarity.

Catalytic activity

2 R'C(R)SH + O2 = R'C(R)S-S(R)CR' + H2O2.

Cofactor

FAD By similarity.

Subunit structure

Interacts with A2.5; this interaction involves formation of a transient disulfide-bonded intermediate, allowing disulfide bond transfer By similarity.

Subcellular location

Virion membrane; Single-pass membrane protein Potential. Note: Associated with crescent membranes, immature virions (IV) and mature virions (MV) By similarity.

Induction

Expressed in the late phase of the viral replicative cycle.

Sequence similarities

Belongs to the poxviridae E10 family.

Contains 1 ERV/ALR sulfhydryl oxidase domain.
