The microsomal fraction of avocado (Persa americana) mesocarp is a rich source of cytochrome P-450 active in the demethylation of xenobiotics. Cytochrome P-450 from this tissue has been purified and well characterized at the molecular level (DP O'Keefe, KJ Leto Leto [1989] Plant Physiol 89: 1141-1149; KR Bozak, H yu, R Sirevag, RE Christoffersen [1990] Proc Natl Acad Sci USA 87:3904-3908). Despite this extensive characterization, the role of the enzyme in vivo was not established. Optical and electron paramagnetic resonance binding studies described heresuggest that the monoterpenoids, nerol, are substrates of avocado cytochrome P-450(spectral dissociation constant of 7.2 and 35 micromolar, respectively). |
