methylglyoxal synthase; Methylglyoxal synthase (MGS) generates methylglyoxal (MG), a toxic metabolite (that may also be a regulatory metabolite and) that is detoxified, prinicipally, through a pathway involving glutathione and glyoxylase I. Totemeyer et al. propose that, during a loss of control over carbon flux, with accumulation of phosphorylated sugars and depletion of phosphate, as might happen during a rapid shift to a richer medium, MGS aids the cell by converting some dihydroxyacetone phosphate (DHAP) to MG and phosphate. This is therefore an alternative to triosephosphate isomerase and the remainder of the glycolytic pathway for the disposal of DHAP during the stress of a sudden increase in available sugars.

 2-116 1.01e-66

Methylglyoxal synthase catalyzes the enolization of dihydroxyacetone phosphate (DHAP) to produce methylglyoxal. The first part of the catalytic mechanism is believed to be similar to TIM (triosephosphate isomerase) in that both enzymes utilize DHAP to form an ene-diolate phosphate intermediate. In MGS, the second catalytic step is characterized by the elimination of phosphate and collapse of the enediolate to form methylglyoxal instead of reprotonation to form the isomer glyceraldehyde 3-phosphate, as in TIM. This is the first reaction in the methylglyoxal bypass of the Embden-Myerhoff glycolytic pathway and is believed to provide physiological benefits under non-ideal growth conditions in bacteria.

The family also includes the C-terminal domain in carbamoyl phosphate synthetase (CPS) where it catalyzes the last phosphorylation of a coaboxyphosphate intermediate to form the product carbamoyl phosphate and may also play a regulatory role. This family also includes inosine monophosphate cyclohydrolase. The known structures in this family show a common phosphate binding site.

MGS-like domain; This domain composes the whole protein of methylglyoxal synthetase and the domain is also found in Carbamoyl phosphate synthetase (CPS) where it forms a regulatory domain that binds to the allosteric effector ornithine. This family also includes inosicase. The known structures in this family show a common phosphate binding site.
