2-C-Methylerythritol 4-phosphate
2-''C''-Methyl--erythritol 4-phosphate (MEP) is an intermediate on the MEP pathway (non-mevalonate pathway) of isoprenoid precursor biosynthesis. It is the first committed metabolite on that pathway on the route to IPP and DMAPP.

It specifically inhibits DXP reductoisomerase, a key enzyme in the non-mevalonate pathway of isoprenoid biosynthesis. It ...

MEP Pathway
The non-mevalonate pathway—also appearing as the mevalonate-independent pathway and the 2-''C''-methyl-D-erythritol 4-phosphate/1-deoxy-D-xylulose 5-phosphate (MEP/DOXP) pathway—is an alternative metabolic pathway for the biosynthesis of the isoprenoid precursors isopentenyl pyrophosphate (IPP) and dimethylallyl pyrophosphate (DMAPP). The currently preferred name for this pathway is the MEP pathway, since MEP is the first committed metabolite on the route to IPP. Isoprenoid precursor biosynthesis The classical mevalonate pathway (MVA pathway or HMG-CoA reductase pathway) is a metabolic pathway for the biosynthesis of isoprenoid precursors: IPP and DMAPP. The MVA pathway is present in most eukaryotes and some bacteria. IPP and DMAPP serve as the basis for the biosynthesis of isoprenoid (terpenoid) molecules used in processes as diverse as protein prenylation, cell membrane maintenance, the synthesis of hormones, protein anchoring and ''N''-glycosylation in all three domains ...
