ENZYME entry: EC 2.3.1.65

Accepted Name
Bile acid-CoA:amino acid N-acyltransferase.
Alternative Name(s)
Amino acid N-choloyltransferase.
BACAT.
BAT.
Cholyl-CoA glycine-taurine N-acyltransferase.
Cholyl-CoA:taurine N-acyltransferase.
Glycine N-choloyltransferase.
Glycine--taurine N-acyltransferase.
Reaction catalysed
Choloyl-CoA + glycine <=> CoA + glycocholate
Comment(s)
  • Also acts on CoA derivatives of other bile acids.
  • Taurine and 2-fluoro-beta-alanine can act as substrates, but more slowly.
  • Can also conjugate fatty acids to glycine and can act as a very-long- chain acyl-CoA thioesterase.
  • Bile-acid--amino-acid conjugates serve as detergents in the gastrointestinal tract, solubilizing long chain fatty acids, mono- and diglycerides, fat-soluble vitamins and cholesterol.
  • This is the second enzyme in a two-step process leading to the conjugation of bile acids with amino acids; the first step is the conversion of bile acids into their acyl-CoA thioesters, which is catalyzed by EC 6.2.1.7.
