General annotation (Comments)

Function

Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. AcsA undergoes a two-step reaction. In the first half reaction, AcsA combines acetate with ATP to form acetyl-adenylate (AcAMP) intermediate. In the second half reaction, it can then transfer the acetyl group from AcAMP to the sulfhydryl group of CoA, forming the product AcCoA By similarity. HAMAP-Rule MF_01123

Catalytic activity

ATP + acetate + CoA = AMP + diphosphate + acetyl-CoA. HAMAP-Rule MF_01123

Cofactor

Magnesium By similarity.

Post-translational modification

Acetylated. Deacetylation by the SIR2-homolog deacetylase activates the enzyme By similarity. HAMAP-Rule MF_01123

Miscellaneous

There is no ortholog for acsA in strain J99. HAMAP-Rule MF_01123

Sequence similarities

Belongs to the ATP-dependent AMP-binding enzyme family.
