General annotation (Comments)

Function

CoA transferase having broad substrate specificity for short-chain acyl-CoA thioesters with the activity decreasing when the length of the carboxylic acid chain exceeds four carbons. Exhibits high activity with acetoacetyl-CoA, propionyl-CoA, crotonoyl-CoA or butyryl-CoA as donors, with acetate as an acceptor. When acetyl-CoA is used as the donor, propionate, acetoacetate, butyrate, isobutyrate, and 4-hydroxybutyrate can be utilized as acceptors but not isovalerate. May play a role in short-chain fatty acid metabolism in E.coli. Ref.3

Catalytic activity

Acyl-CoA + acetate = a fatty acid anion + acetyl-CoA. Ref.3

Subunit structure

Homotetramer; dimer of dimers. Ref.3

Miscellaneous

Formation of the covalent enzyme-CoA thioester intermediate proceeds via an unstable anhydride species formed between the carboxylate group of the catalytic glutamate of the enzyme and the carbonyl carbon of the thioester linkage of the substrate.

Sequence similarities

Belongs to the 3-oxoacid CoA-transferase family.

Mass spectrometry

Molecular mass is 59628 Da from positions 1 - 531. Determined by ESI. Ref.3
