CC -!- FUNCTION: Catalyzes the reversible formation of acetate and ATP from
CC acetyl-CoA by using ADP and phosphate. Can use other substrates such as
CC phenylacetyl-CoA, indoleacetyl-CoA and isobutyryl-CoA, but not
CC succinyl-CoA. Seems to be involved primarily in the degradation of
CC aryl-CoA esters to the corresponding acids. Participates in the
CC conversion of acetyl-CoA to acetate and in the degradation of branched-
CC chain amino acids via branched-chain-acyl-CoA esters.
CC {ECO:0000269|PubMed:8830684}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=acetate + ATP + CoA = acetyl-CoA + ADP + phosphate;
