Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (FLK_STRCT | Q1EMV2)
molecular function
    GO:0016289    CoA hydrolase activity    Catalysis of the reaction: X-CoA + H2O = X + CoA; X may be any group.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
biological process
    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.
