the reaction does not exhibit burst kinetics for either substrate, indicating that product release is not rate-limiting, the rearrangement step, which precedes hydride transfer, is rate-limiting for 1-deoxy-D-xylulose 5-phosphate but becomes partially ratelimiting for 1-fluoro-1-deoxy-D-xylulose 5-phosphate, thus, rearrangement appears to be enhanced by substitution of a hydrogen atom in the methyl group of 1-deoxy-D-xylulose 5-phosphate by fluorine, consistent with a retro-aldol/aldol mechanism for the rearrangement during conversion of 1-deoxy-D-xylulose 5-phosphate to 2-C-methyl-D-erythritol 4-phosphate |
