Protein

Acetate CoA-transferase YdiF

Gene
ydiF, Z2722, ECs2401
Organism
Escherichia coli O157:H7
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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.1 Publication

Catalytic activityi

Acyl-CoA + acetate = a fatty acid anion + acetyl-CoA.1 Publication
