Chain A,B   (PEPM_MYTED | P56839)
molecular function
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0016853    isomerase activity    Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0050188    phosphoenolpyruvate mutase activity    Catalysis of the reaction: phosphoenolpyruvate = 3-phosphonopyruvate.
biological process
    GO:0032923    organic phosphonate biosynthetic process    The chemical reactions and pathways resulting in the formation of phosphonates, any organic compound containing one or more C-PO(OH)2 or C-PO(OR)2 (with R=alkyl, aryl) groups. Synthesis of phosphonic acid itself, an inorganic compound without the biochemically relevant C-P bond, is not included.
