ID   1.14.18.4
DE   phosphatidylcholine 12-monooxygenase.
AN   oleate Delta(12)-hydroxylase.
AN   ricinoleic acid synthase.
CA   1-acyl-2-(9Z)-octadecenoyl-sn-glycero-3-phosphocholine + 2 Fe(II)-
CA   [cytochrome b5] + 2 H(+) + O2 = 1-acyl-2-[(R)-12-hydroxyoleoyl]-
CA   sn-glycero-3-phosphocholine + 2 Fe(III)-[cytochrome b5] + H2O.
CC   -!- The enzyme, characterized from the plant Ricinus communis (castor
CC       bean), is involved in production of the 12-hydroxylated fatty acid
CC       ricinoleate.
CC   -!- The enzyme requires a cytochrome b5 as the electron donor.
CC   -!- Formerly EC 1.14.13.26.
