General annotation (Comments)
| Function | Catalyzes the NADPH-dependent reduction of glyoxylate and hydroxypyruvate into glycolate and glycerate, respectively. Inactive towards 2-oxo-D-gluconate, 2-oxoglutarate, oxaloacetate and pyruvate. Only D- and L-glycerate are involved in the oxidative activity with NADP. Activity with NAD is very low. HAMAP MF_01666 |
| Catalytic activity | Glycolate + NADP+ = glyoxylate + NADPH. Ref.4 D-glycerate + NAD(P)+ = hydroxypyruvate + NAD(P)H. Ref.4 |
| Subcellular location | Cytoplasm Probable. |
| Induction | Constitutively expressed. Ref.4 |
| Sequence similarities | Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family. GhrA subfamily. |
| biophysicochemical properties | Kinetic parameters: The catalytic efficiency is better for glyoxylate than hydroxypyruvate with NADPH as electron donor. KM=0.6 mM for glyoxylate (at 25 degrees Celsius and pH 7) HAMAP MF_01666 KM=1.0 mM for hydroxypyruvate (at 25 degrees Celsius and pH 7) Vmax=120 µmol/min/mg enzyme with glyoxylate as substrate (at 25 degrees Celsius and pH 7) Vmax=20 µmol/min/mg enzyme with hydroxypyruvate as substrate (at 25 degrees Celsius and pH 7) pH dependence: Optimum pH is 7.0. |
