EC 6.2.1.35 Details

show Brenda entry

EC number

6.2.1.35

Accepted name

acetate—[acyl-carrier protein] ligase

Reaction

ATP + acetate + an [acyl-carrier protein] = AMP + diphosphate + an acetyl-[acyl-carrier protein]

Other name(s)

HS-acyl-carrier protein:acetate ligase, [acyl-carrier protein]:acetate ligase, MadH, ACP-SH:acetate ligase

Systematic name

acetate:[acyl-carrier-protein] ligase (AMP-forming)

Comment

This enzyme, from the anaerobic bacterium Malonomonas rubra, is a component of the multienzyme complex EC 7.2.4.4, biotin-dependent malonate decarboxylase. The enzyme uses the energy from hydrolysis of ATP to convert the thiol group of the acyl-carrier-protein-bound 2′-(5-phosphoribosyl)-3′-dephospho-CoA prosthetic group into its acetyl thioester [2].
