DE   Methylsterol monooxygenase.
AN   4-methylsterol oxidase.
AN   Methylsterol hydroxylase.
CA   (1) 4,4-dimethyl-5-alpha-cholest-7-en-3-beta-ol + NAD(P)H + O(2) =
CA   4-beta-hydroxymethyl-4-alpha-methyl-5-alpha-cholest-7-en-3-beta-ol +
CA   NAD(P)(+) + H(2)O.
CA   (2) 4-beta-hydroxymethyl-4-alpha-methyl-5-alpha-cholest-7-en-3-beta-ol +
CA   NAD(P)H + O(2) = 3-beta-hydroxy-4-beta-methyl-5-alpha-cholest-7-ene-4-
CA   alpha-carbaldehyde + NAD(P)(+) + 2 H(2)O.
CA   (3) 3-beta-hydroxy-4-beta-methyl-5-alpha-cholest-7-ene-4-alpha-
CA   carbaldehyde + NAD(P)H + O(2) = 3-beta-hydroxy-4-beta-methyl-5-alpha-
CA   cholest-7-ene-4-alpha-carboxylate + NAD(P)(+) + H(2)O.
CC   -!- Requires cytochrome b5.
CC   -!- Also acts on 4-alpha-methyl-5-alpha-cholest-7-en-3-beta-ol.
CC   -!- The sterol can be based on cycloartenol as well as lanosterol.
CC   -!- Formerly EC 1.14.99.16.
