Chain A,B,C,D   (Q9X266_THEMA | Q9X266)
molecular function
    GO:0008732    L-allo-threonine aldolase activity    Catalysis of the reaction: L-allo-threonine = glycine + acetaldehyde.
    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: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:0004793    threonine aldolase activity    Catalysis of the reaction: L-threonine = glycine + acetaldehyde.
biological process
    GO:0006520    cellular amino acid metabolic process    The chemical reactions and pathways involving amino acids, carboxylic acids containing one or more amino groups, as carried out by individual cells.
    GO:0006545    glycine biosynthetic process    The chemical reactions and pathways resulting in the formation of glycine, aminoethanoic acid.
    GO:0006567    threonine catabolic process    The chemical reactions and pathways resulting in the breakdown of threonine (2-amino-3-hydroxybutyric acid), a polar, uncharged, essential amino acid found in peptide linkage in proteins.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
