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

VvDxr residues S186, H209, S222, N227 and K228 may participate in binding of the DXP substrate's phosphate moiety. These residues are conserved. H209 is a part of a flexible loop (209-HPXWXMG-115) that closes on the active site upon substrate binding. While H209 interacts with the phosphate group, W211 and M213 shield the remaining part of Dxp from solvent
