    The reaction mechanism of methylglyoxal synthase (MGS) is believed to be similar to that of triosephosphate isomerase (TIM). Both enzymes utilise dihydroxyacetone phosphate (DHAP) to form an enediol(ate) phosphate intermediate as the first step of their reaction pathways. However, the second catalytic step in the MGS reaction pathway is characterized by the elimination of phosphate and collapse of the enediol(ate) to form methylglyoxal instead of reprotonation to form the isomer glyceraldehyde 3-phosphate.
