D-threitol + NADP+ = D-erythrulose + NADPH + H+
in an early reference the enzymatic reaction product of D-erythrulose was incorrectly identified as erythritol, gas-liquid and thin-layer chromatographic data have since confirmed the product to be D-threitol, not erythritol, for this reason the systematic name D-threitol:NADP+ oxidoreductase is now used instead of erythritol:NADP+ oxidoreductase

D-threitol + NAD(P)+
in reference 2 the enzymatic reaction product of D-erythrulose is incorrectly identified as erythritol, gas-liquid and thin-layer chromatographic data have confirmed the product to be D-threitol, not erythritol, for this reason the systematic name D-threitol:NADP+ oxidoreductase should be used instead of erythritol:NADP+ oxidoreductase which has been designated by the IUB Enzyme commission

D-erythrulose + NAD(P)H
the equilibrium of the reaction strongly favors the reduction of D-erythrulose, the reverse reaction is slightly detectable when carried out at pH 7.5-9.0 using NADP+, erythritol does not serve as substrate
