EC 1.1.1.372

Accepted name: D/L-glyceraldehyde reductase

Reaction: (1) glycerol + NADP+ = L-glyceraldehyde + NADPH + H+
(2) glycerol + NADP+ = D-glyceraldehyde + NADPH + H+

Other name(s): gld1-(gene name); gaaD-(gene name)

Systematic name: glycerol:NADP+ oxidoreductase (D/L-glyceraldehyde-forming)

Comments: The enzyme takes part in a D-galacturonate degradation pathway in the fungi Aspergillus niger-and Trichoderma reesei-(Hypocrea jecorina). It has equal activity with D- and L-glyceraldehyde, and can also reduce glyoxal and methylglyoxal. The reaction is only observed in the direction of glyceraldehyde reduction.
