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.
