ID   1.14.21.6
DE   Lathosterol oxidase.
AN   5-DES.
AN   Delta(7)-sterol 5-desaturase.
AN   Delta(7)-sterol Delta(5)-dehydrogenase.
AN   Delta(7)-sterol-C5(6)-desaturase.
AN   Lathosterol 5-desaturase.
CA   5-alpha-cholest-7-en-3-beta-ol + NAD(P)H + O(2) = cholesta-5,7-dien-3-
CA   beta-ol + NAD(P)(+) + 2 H(2)O.
CC   -!- This enzyme catalyzes the introduction of a C5 double bond into the B
CC       ring of Delta(7)-sterols to yield the corresponding
CC       Delta(5,7)-sterols in mammals, yeast and plants.
CC   -!- Forms part of the plant sterol biosynthesis pathway.
CC   -!- Formerly EC 1.3.3.2.
