Protein attributes

Sequence length	220 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	May protect the virus and component of infected cells from oxidative damage by peroxides whose formation may be stimulated by infection. Ref.1
Catalytic activity	2 glutathione + H2O2 = glutathione disulfide + 2 H2O.
Miscellaneous	This enzyme has been acquited by lateral transfer from its human host and has retained 74% identity with cellular GPX1.
Sequence similarities	Belongs to the glutathione peroxidase family.
