ID 1.14.14.145 DE abieta-7,13-dien-18-ol hydroxylase. AN abietadienol hydroxylase. AN CYP720B1. CA abieta-7,13-dien-18-ol + 2 O2 + 2 reduced [NADPH--hemoprotein reductase] CA = abieta-7,13-dien-18-oate + 3 H(+) + 3 H2O + 2 oxidized [NADPH- CA -hemoprotein reductase]. CC -!- A cytochrome P450 (heme-thiolate) protein. CC -!- This enzyme catalyzes a step in the pathway of abietic acid CC biosynthesis. CC -!- The activity has been demonstrated in cell-free stem extracts of CC Abies grandis (grand fir) and Pinus contorta (lodgepole pine), CC and the gene encoding the enzyme has been identified in Pinus taeda CC (loblolly pine). CC -!- The recombinant enzyme catalyzes the oxidation of multiple diterpene CC alcohol and aldehydes, including levopimaradienol, isopimara-7,15- CC dienol, isopimara-7,15-dienal, dehydroabietadienol and CC dehydroabietadienal. CC -!- It is not able to oxidize abietadiene. CC -!- Formerly EC 1.14.13.109. DR Q50EK6, C72B1_PINTA; //
