physiological function | the NADPH/NADH-dependent glyoxylate/hydroxypyruvate reductases (GRHPR) regulate the glyoxylate content within cells, highly conserved enzymes with a dual activity as they are able to reduce glyoxylate to glycolate and to convert hydroxypyruvate into D-glycerate. The enzyme from the hyperthermophilic archaeon, displays a higher preference for glyoxylate than hydroxypyruvate in presence of NADH, whereas no activity is detected in presence of NADPH | Pyrococcus furiosus |
