Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (ATOD_ECOLI | P76458)
molecular function
    GO:0008410    CoA-transferase activity    Catalysis of the transfer of a coenzyme A (CoA) group from one compound (donor) to another (acceptor).
    GO:0008775    acetate CoA-transferase activity    Catalysis of the reaction: acyl-CoA + acetate = a fatty acid anion + acetyl-CoA.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0006631    fatty acid metabolic process    The chemical reactions and pathways involving fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis.
    GO:0006629    lipid metabolic process    The chemical reactions and pathways involving lipids, compounds soluble in an organic solvent but not, or sparingly, in an aqueous solvent. Includes fatty acids; neutral fats, other fatty-acid esters, and soaps; long-chain (fatty) alcohols and waxes; sphingoids and other long-chain bases; glycolipids, phospholipids and sphingolipids; and carotenes, polyprenols, sterols, terpenes and other isoprenoids.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    GO:0046459    short-chain fatty acid metabolic process    The chemical reactions and pathways involving fatty acids with a chain length of less than C6.
