The Role of Lys-12 in Catalysis by Triosephosphate Isomerase: A Two-Part Substrate Approach

We report that the K12G mutation at triosephosphate isomerase (TIM) from Saccharomyces cerevisiae results in: (1) A ca. 50-fold increase in K(m) for the substrate glyceraldehyde 3-phosphate (GAP) and a 60-fold increase in K(i) for competitive inhibition by the intermediate analog 2-phosphoglycolate,...
