-
 attempt to examine the specificity of the active site of DHDPS, co-crystallization with the substrate analogue oxaloacetate, solution of the protein structure indicates that pyruvate rather than oxaloacetic acid bounds in the active site, decarboxylation of oxaloacetate not catalysed by DHDPS, rate of pyruvate production independent of DHDPS concentration, indicating that the decarboxylation of oxaloacetate is occurring by a spontaneous and enzyme-independent mechanism, confirmed by kinetic analysis Escherichia coli
