Functional Family Acetate CoA-transferase YdiF

Enzyme Information

2.8.3.8
Acetate CoA-transferase.
based on mapping to UniProt Q8X5X6
Acyl-CoA + acetate = a fatty acid anion + acetyl-CoA.
-!- The enzyme belongs to family I of CoA-transferases, which operate with a ping-pong kinetic mechanism. -!- The reaction takes place in two half-reactions and involves the formation of a CoA thioester intermediate with a glutamate residue. -!- Unlike EC 2.8.3.9, this enzyme exhibits maximal activity using acetate as the CoA acceptor. -!- Substrate range depends on the specific enzyme. -!- Typical substrates include butanoyl-CoA and pentanoyl-CoA.
