IUBMB Comments
2-C-methyl-D-erythritol-4-phosphate:NADP+ oxidoreductase (isomerizing)
The enzyme requires Mn2+, Co2+ or Mg2+ for activity, with the first being most effective. The enzyme from several eubacteria, including Escherichia coli, forms part of an alternative nonmevalonate pathway for terpenoid biosynthesis (for diagram, {terp/nonMVA}). The mechanism has been shown to be a retroaldol/aldol reaction [2].
