In enzymology, a methylglyoxal synthase (EC 4.2.3.3) is an enzyme that catalyzes the chemical reaction

glycerone phosphate \rightleftharpoons methylglyoxal + phosphate

Hence, this enzyme has one substrate, glycerone phosphate, and two products, methylglyoxal and phosphate.

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is glycerone-phosphate phosphate-lyase (methylglyoxal-forming). Other names in common use include methylglyoxal synthetase, and glycerone-phosphate phospho-lyase. This enzyme participates in pyruvate metabolism.

Structural studies

As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes 1B93, 1EGH, 1IK4, 1S89, 1S8A, 1VMD, and 1WO8.
