Chain X   (AEEP_ECOLI | P51981)
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:0016855    racemase and epimerase activity, acting on amino acids and derivatives    Catalysis of a reaction that alters the configuration of one or more chiral centers in an amino acid.
biological process
    GO:0071555    cell wall organization    A process that results in the assembly, arrangement of constituent parts, or disassembly of the cell wall, the rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal and most prokaryotic cells, maintaining their shape and protecting them from osmotic lysis.
    GO:0009063    cellular amino acid catabolic process    The chemical reactions and pathways resulting in the breakdown of amino acids, organic acids containing one or more amino substituents.
    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:0009254    peptidoglycan turnover    The continual breakdown and regeneration of peptidoglycan required to maintain the cell wall.
