SYSTEMATIC NAME
IUBMB Comments
lithocholate:NADP+ 3-oxidoreductase
This bacterial enzyme is involved in the modification of secondary bile acids to form 3beta-bile acids (also known as iso-bile acids) via a 3-oxo intermediate. The enzyme catalyses a reversible reaction in vitro. Also acts on related bile acids. cf. EC 1.1.1.52, 3alpha-hydroxycholanate dehydrogenase (NAD+).
