Chain A,B   (HCHA_ECOLI | P31658)
molecular function
    GO:0019172    glyoxalase III activity    Catalysis of the reaction: methylglyoxal + H2O = D-lactate.
    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:0016811    hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds, in linear amides    Catalysis of the hydrolysis of any non-peptide carbon-nitrogen bond in a linear amide.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0016790    thiolester hydrolase activity    Catalysis of the reaction: RCO-SR' + H2O = RCOOH + HSR'. This reaction is the hydrolysis of a thiolester bond, an ester formed from a carboxylic acid and a thiol (i.e., RCO-SR'), such as that found in acetyl-coenzyme A.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0019249    lactate biosynthetic process    The chemical reactions and pathways resulting in the formation of lactate, the anion of lactic acid.
    GO:0019243    methylglyoxal catabolic process to D-lactate via S-lactoyl-glutathione    The chemical reactions and pathways resulting in the breakdown of methylglyoxal, CH3-CO-CHO, into D-lactate via the intermediate S-lactoyl-glutathione. Glutathione is used in the first step of the pathway and then regenerated in the second step.
    GO:0042026    protein refolding    The process carried out by a cell that restores the biological activity of an unfolded or misfolded protein, using helper proteins such as chaperones.
    GO:0030091    protein repair    The process of restoring a protein to its original state after damage by such things as oxidation or spontaneous decomposition of residues.
    GO:0010447    response to acidic pH    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a pH stimulus with pH < 7. pH is a measure of the acidity or basicity of an aqueous solution.
    GO:0051595    response to methylglyoxal    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a methylglyoxal stimulus. Methylglyoxal is a 2-oxoaldehyde derived from propanal.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
