1.14.14.143 (+)-menthofuran synthase
IUBMB Comments
A cytochrome P-450 (heme-thiolate) protein. The conversion of substrate into product involves the hydroxylation of the syn-methyl (C9), intramolecular cyclization to the hemiketal and dehydration to the furan . This is the second cytochrome P-450-mediated step of monoterpene metabolism in peppermint, with the other step being catalysed by EC 1.14.14.99, (S)-limonene 3-monooxygenase .

the enzyme is involved in the terpene biosynthesis pathway, overview
physiological function
Trichoderma viride Tv-1511-inoculated peppermint produces higher concentrations of menthone, menthol, and pulegone and lower concentrations of menthofuran than uninoculated seedlings. In T. viride Tv-1511-incubated peppermint, pretreatment with MAPK inhibitor PD98059 results in the marked increase in the transcript of menthofuran synthase
