   Legend:   → Mismatch (orange background)
  - → Gap (green background, '-', border residues have a numbering label)
    → Modified Residue (blue background, lower-case, 'x' indicates undefined single-letter code, labelled with number + name)
  x → Chemical Group (purple background, 'x', labelled with number + name, e.g. ACE or NH2)
  extra numbering lines below/above indicate numbering irregularities and modified residue names etc., number ends below/above '|'

Chain A,B,C,D,E,F   (MGSA_THET8 | Q5SHD6)
molecular function
    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:0008929    methylglyoxal synthase activity    Catalysis of the reaction: glycerone phosphate = methylglyoxal + phosphate.
biological process
    GO:0019242    methylglyoxal biosynthetic process    The chemical reactions and pathways resulting in the formation of methylglyoxal, CH3-CO-CHO, the aldehyde of pyruvic acid.
