Reaction catalysed
  • ATP + cholate + CoA = AMP + choloyl-CoA + diphosphate
  • (25R)-3alpha,7alpha,12alpha-trihydroxy-5beta-cholestan-26-oate + ATP + CoA = (25R)-3alpha,7alpha,12alpha-trihydroxy-5beta-cholestan-26-oyl-CoA + AMP + diphosphate
  • This membrane-bound enzyme catalyzes the first step in the conjugation of bile acids with amino acids, converting bile acids into their acyl-CoA thioesters.
  • The second step involves EC and converts the acyl-CoA thioester into the corresponding N-acyl amidate by conjugation with glycine or taurine.
  • Chenodeoxycholate, deoxycholate, lithocholate and trihydroxycoprostanoate can also act as substrates.
  • Formerly EC
