negatively regulates acetyl-CoA synthetase activity acetyl-CoA synthetase acetyltransferase activity GO:0043894 protein acetyltransferase activity Catalysis of the acetylation of a lysine of the enzyme acetyl-CoA ligase, using acetyl-CoA as substrate. In Bacillus subtilis, this is Lys609, but it may correspond to another position in orthologs. This acetylation results in inhibition of acetyl-CoA synthetase. molecular_function Pat enzyme acetyl CoA synthetase acetyltransferase activity acetate-CoA ligase acetyltransferase activity acetate CoA ligase acetyltransferase activity ligase inhibitor activity protein-lysine-acetyltransferase activity
