GENERAL INFORMATION
ORGANISM
UNIPROT
COMMENTARY
LITERATURE
evolution
the enzyme belongs to the beta-HAD (beta-hydroxyacid dehydrogenase) protein family. AtHPR2 and AtHPR3 are 45% identical to each other at the amino acid level, but only 19-25% identical to AtHPR1, the NADH-dependent form, and 8-9% identical to the AtGLYRs. None of the AtHPRs contains the active-site residues conserved in AtGLYR1 and AtGLYR2, indicating that the sites responsible for reducing glyoxylate differ greatly between the AtGLYRs and AtHPRs; the enzyme belongs to the beta-HAD (beta-hydroxyacid dehydrogenase) protein family.

physiological function
physiological function
-
in the dark, cytokinins mimic the regulatory effect of light upon algal cell division, metabolite content and stimulate carbon recycling for Calvin cycle reactions by enhancing of light-dependent NADH-HPR activity, regulation, overview
physiological function
deletion of any of the core enzymes of the photorespiratory cycle, one of the major pathways of plant primary metabolism, results in severe air-sensitivity of the respective mutants with the exception of the peroxisomal enzyme hydroxypyruvate reductase, HPR1, due to the existence of a second hydroxypyruvate reductase, HPR2, in the cytosol, overview. The enzyme provides a cytosolic bypass to the photorespiratory core cycle in Arabidopsis thaliana
physiological function
deletion of isoform HPR3 results in slightly altered leaf concentrations of the photorespiratory intermediates HP, glycerate, and glycine, indicating a disrupted photorespiratory flux, but not in visible alteration of the phenotype.The combined deletion of of isoforms HPR1, HPR2, and HPR3 causes increased growth retardation, decreased photochemical efficiency, and reduced oxygen-dependent gas exchange in comparison with the hpr1hpr2 double mutant. Isoform HPR3 could provide a compensatory bypass for the reduction of hydroxypyruvate and glyoxylate within the chloroplast
physiological function
hydroxypyruvate reductase activity is important in the recycling of metabolites derived during photorespiration; hydroxypyruvate reductase activity is important in the recycling of metabolites derived during photorespiration; hydroxypyruvate reductase activity is important in the recycling of metabolites derived during photorespiration
physiological function
upregulation of glyoxylate reductase/hydroxypyruvate reductase is associated with intestinal epithelial cells apoptosis in trinitrobenzenesulfonic acid-induced colitis

Deletion of HPR2 results in elevated levels of hydroxypyruvate and other metabolites in leaves, photosynthetic gas exchange is slightly altered, especially under long-day conditions. Deletion of HPR1 does not show a severe phenotype, overview. The combined deletion of HPR1 and HPR2 is detrimental to air-grown mutants and alters steady state metabolite profiles, phenotypes, overview. The most prominent naturally occuring mutation causes the decrease in Ala content coupled with enhanced levels of Arg, Asn, and Asp in the hpr1 mutant and the double knockout plant; HPR1 knockout plants show slight visually noticeable impairments in air. Under shorter daylengths of 8 h, somewhat slower growth of the hpr1 mutants than of the wild-type, in combination with an approximately 4-week delay in bolting. Combined deletion of both HPR1 and HPR2 (EC 1.1.1.81) results in distinct air-sensitivity and a dramatic reduction in photosynthetic performance
