additional information a retroaldol/aldol mechanism for the DXR catalyzed rearrangement of 1-deoxy-D-xylulose 5-phosphate to 2-C-methyl-D-erythritol 4-phosphate. DXR first cleaves the C3-C4 bond of 1-deoxy-D-xylulose 5-phosphate in a retroaldol manner to generate a three-carbon and a two-carbon phosphate bimolecular intermediate. These two species are then reunited by an aldol reaction to form a new C-C bond, yielding the same aldehyde intermediate methylerythrose phosphate. Subsequent reduction of methylerythrose phosphate by NADPH affords 2-C-methyl-D-erythritol 4-phosphate synthetic construct ?
