General annotation (Comments)

Function

Catalyzes the conversion of acetate into acetyl-CoA (AcCoA), an essential intermediate at the junction of anabolic and catabolic pathways. Acs undergoes a two-step reaction. In the first half reaction, Acs 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

Enables the cell to use acetate during aerobic growth to generate energy via the TCA cycle, and biosynthetic compounds via the glyoxylate shunt. Acetylates CheY, the response regulator involved in flagellar movement and chemotaxis By similarity. HAMAP-Rule MF_01123

Catalytic activity

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

Cofactor

Magnesium By similarity. HAMAP-Rule MF_01123 SAAS SAAS020845

Post-translational modification

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

Sequence similarities

Belongs to the ATP-dependent AMP-binding enzyme family. HAMAP-Rule MF_01123
