GENERAL INFORMATION

UNIPROT ACCESSION NO.
COMMENTARY
LITERATURE
physiological function
-
succinic semialdehyde and glyoxylate are typically generated in leaves via two distinct metabolic pathways, 4-aminobutyrate and glycolate respectively. GLYR isozymes function in the detoxification of both aldehydes during stress and contribute to redox balance, overview
physiological function
Q9LSV0
GLYR1 scavenges succinic semialdehyde and glyoxylate that escape from mitochondria and peroxisomes, respectively
metabolism
-
the enzyme is involved in the glycolate metabolism, as well as the 4-hydroxybutyrate production and the GABA shunt pathway, overview
additional information
Q9LSV0
due to the glutamate at the -1 position, GLYR1 C-terminal tripeptide, -SRE, does not function as a type 1 peroxisomal targeting signal, PTS1. GLYR1 is not relocalized from the cytosol to peroxisomes in response to abiotic stress

LITERATURE
exclusive localization in the cytosol of transgenic Arabidopsis plants co-expressing GFP-GLYR1 and and Cherry-PTS1, a fusion protein consisting of the Cherry fluorescent protein linked to the PTS1 of the peroxisomal enzyme hydroxypyruvate reductase. Expression of N-terminal GFP-tagged or Myc-tagged GLYR1 in tobacco BY-2 cell cytosol. GFP- or Myc-tagged GLYR1 is competent, at least partially, for import into peroxisomes, since replacement of the C-terminal glutamate in GLYR1 with leucine, which yields a canonical PTS1 (i.e., a C-terminal small-basic-hydrophobic tripeptide motif), results in the modified fusion protein (GFPGLYR1-E to L and Myc-GLYR1-E to L) being dual localized to the cytosol and peroxisomes in BY-2 cells

construction of a E141N/Q313E mutant formate dehydrogenase which gains glyoxylate reductase activity improved through enhancement of the hydrogen transfer step in the catalytic process, while the replacement induces no marked activity toward other 2-koxoacid substrates, and diminishes the enzyme's activity as to formate oxidation, substrate specificity and kinetic switch of the mutant, overview
