 It can then be converted to 2-phosphoglycerate, which can then enter into glycolysis, gluconeogenesis, or the serine pathway.As the name suggests, in addition to the glycerate dehydrogenase and hydroxypyruvate reductase activity, the protein also exhibits glyoxylate reductase activity.The ability of GRHPR to reduce glyoxylate to glycolate is found in other glycerate dehydrogenase homologs as well.
