Chain A,B,C,D,E,F (MGSA_ECOLI | P0A731)

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.
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.
