In enzymology, a 3α,7α-dihydroxy-5β-cholestanate—CoA ligase (EC 6.2.1.28) is an enzyme that catalyzes the chemical reaction
- ATP + (25R)-3alpha,7alpha-dihydroxy-5beta-cholestan-26-oate + CoA AMP + diphosphate + (25R)-3alpha,7alpha-dihydroxy-5beta-cholestanoyl-CoA
The 3 substrates of this enzyme are ATP, (25R)-3alpha,7alpha-dihydroxy-5beta-cholestan-26-oate, and CoA, whereas its 3 products are AMP, diphosphate, and (25R)-3alpha,7alpha-dihydroxy-5beta-cholestanoyl-CoA.
This enzyme belongs to the family of ligases, specifically those forming carbon-sulfur bonds as acid-thiol ligases. The systematic name of this enzyme class is (25R)-3alpha,7alpha-dihydroxy-5beta-cholestan-26-oate:CoA ligase (AMP-forming). Other names in common use include 3alpha,7alpha-dihydroxy-5beta-cholestanoyl coenzyme A synthetase, DHCA-CoA ligase, and 3alpha,7alpha-dihydroxy-5beta-cholestanate:CoA ligase (AMP-forming). This enzyme participates in bile acid biosynthesis.
