P450 cytochrome pathway
This has been proven through thorough analysis of various CYP P450s in jasmonic acid and phytoalexin pathways. Cytochrome P450 aromatic O-demethylase, which is made of two distinct promiscuous parts: a cytochrome P450 protein (GcoA) and three domain reductase, is significant for its ability to convert … See more Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases.
