Sysname
3alpha,7alpha,12alpha-trihydroxy-5beta-cholanoyl-CoA:propanoyl-CoA C-acyltransferase
Reaction(IUBMB)
3alpha,7alpha,12alpha-trihydroxy-5beta-cholanoyl-CoA + propanoyl-CoA = CoA + 3alpha,7alpha,12alpha-trihydroxy-24-oxo-5beta-cholestanoyl-CoA [RN:
R03719 ]
Reaction(KEGG)
Substrate
3alpha,7alpha,12alpha-trihydroxy-5beta-cholanoyl-CoA [CPD:
C01794 ];
propanoyl-CoA [CPD:
C00100 ]
Product
CoA [CPD:
C00010 ];
3alpha,7alpha,12alpha-trihydroxy-24-oxo-5beta-cholestanoyl-CoA [CPD:
C05467 ]
Comment
Also acts on dihydroxy-5beta-cholestanoyl-CoA and other branched chain acyl-CoA derivatives. The enzyme catalyses the penultimate step in the formation of bile acids. The bile acid moiety is transferred from the acyl-CoA thioester (RCO-SCoA) to either glycine or taurine (NH2R') by EC
2.3.1.65 , bile acid-CoA:amino acid N-acyltransferase [3].
History
EC 2.3.1.176 created 2005 (EC 2.3.1.154 created 2000, incorporated 2015)
Pathway
ec00120 Primary bile acid biosynthesis
ec01040 Biosynthesis of unsaturated fatty acids
Orthology
K08764 sterol carrier protein 2
