- 2-C-metil-D-eritritol 4-fosfat + NADP+ 1-dezoksi-D-ksiluloza 5-fosfat + NADPH + H+
Za delovanje ovog enzima su neohodni Mn2+, Co2+ ili Mg2+, pri čemu je mangan najefektivniji. Enzim iz nekoliko eubakterija, uključujući Escherichia coli, formira deo alternativnog nemevalonatnog puta za biosintezu terpenoida.
