Reaction: CYP17A1 cleaves 17aHPROG to ANDST

- in pathway: Androgen biosynthesis
17Alpha-hydroxyprogesterone (17aHPROG), NADPH + H+, and O2 react to form 4-Androstene-3, 17-dione (ANDST), NADP+, H2O, and acetaldehyde. Steroid 17 alpha hydroxylase/17,20 lyase (CYP17A1), which also catalyzes 17-alpha-hydroxylation, catalyzes this lyase reaction.

NADP+ [cytosol]
ANDST [cytosol]
