lathosterol oxidase; C-5 sterol desaturase; delta(7)-sterol 5-desaturase; lathosterol 5-desaturase; sterol-C5-desaturase (SC5D, SC5DL)

Function: - catalyzes dehydrogenation of lathosterol to introduce C5-6 double bond 5-alpha-cholest-7-en-3-beta-ol + NADPH + O2 cholesta-5,7-dien-3-beta-ol + NADP+ + 2 H2O Cofactor: iron Structure: - the histidine box domains may contain active site &/or metal ion binding site Compartment: endoplasmic reticulum membrane Pathology: - defects in SC5DL are the cause of lathosterolosis
