Functional specificities of methylglyoxal synthase and triosephosphate isomerase: a combined QM/MM analysis.

Combined SCC-DFTB/CHARMM calculations were carried out to analyze the origin for the functional specificities of triosephosphate isomerase (TIM) and methylglyoxal synthase (MGS). The two enzymes bind to the same substrate, dihydroxyacetone phosphate (DHAP), and have rather similar active sites. However, they catalyze different reactions; TIM catalyzes the… CONTINUE READING
