Enzyme Information

1.1.1.267

1-deoxy-D-xylulose-5-phosphate reductoisomerase.

based on mapping to UniProt P45568

2-C-methyl-D-erythritol 4-phosphate + NADP(+) = 1-deoxy-D-xylulose 5-phosphate + NADPH.

-!- The enzyme from several eubacteria, including Escherichia coli, forms part of an alternative nonmevalonate pathway for terpenoid biosynthesis. -!- The mechanism has been shown to be a retroaldol/aldol reaction.
