General annotation (Comments)

Function	Cytochromes P450 are a group of heme-thiolate monooxygenases. This isozyme seems to be implicated in olfaction.
Catalytic activity	RH + reduced flavoprotein + O2 = ROH + oxidized flavoprotein + H2O.
Cofactor	Heme group By similarity.
Subcellular location	Endoplasmic reticulum membrane; Peripheral membrane protein. Microsome membrane; Peripheral membrane protein.
Tissue specificity	Olfactory epithelium.
Sequence similarities	Belongs to the cytochrome P450 family.
