CC -!- FUNCTION: Catalyzes the NADPH-dependent reduction of glyoxylate to
CC glycolate as well as succinic semialdehyde (SSA) to gamma-
CC hydroxybutyrate in vitro. May function in redox homeostasis and play a
CC role in oxidative stress tolerance by detoxifying glyoxylate and SSA
CC generated in glycolate metabolism and GABA metabolism, respectively.
CC {ECO:0000269|PubMed:18495639}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=glycolate + NADP(+) = glyoxylate + H(+) + NADPH;
CC Xref=Rhea:RHEA:10992, ChEBI:CHEBI:15378, ChEBI:CHEBI:29805,
CC ChEBI:CHEBI:36655, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=1.1.1.79;
CC Evidence={ECO:0000269|PubMed:18495639};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=4-hydroxybutanoate + NADP(+) = H(+) + NADPH + succinate
CC semialdehyde; Xref=Rhea:RHEA:26381, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16724, ChEBI:CHEBI:57706, ChEBI:CHEBI:57783,
CC ChEBI:CHEBI:58349; EC=1.1.1.n11;
CC Evidence={ECO:0000269|PubMed:18495639};
CC -!- ACTIVITY REGULATION: The ratio of NADPH/NADP(+) may regulate enzymatic
CC activity. {ECO:0000305}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=34 uM for glyoxylate (check for NADPH)
CC {ECO:0000269|PubMed:18495639};
CC KM=8.96 mM for succinate semialdehyde {ECO:0000269|PubMed:18495639};
CC KM=34 uM for NADPH (in the presence of glyoxylate as cosubstrate)
CC {ECO:0000269|PubMed:18495639};
CC KM=12 uM for NADPH (in the presence of succinate semialdehyde as
CC cosubstrate) {ECO:0000269|PubMed:18495639};
CC Vmax=40.6 umol/min/mg enzyme toward glyoxylate
CC {ECO:0000269|PubMed:18495639};
CC Vmax=30.7 umol/min/mg enzyme toward succinate semialdehyde
CC {ECO:0000269|PubMed:18495639};
CC pH dependence:
CC Optimum pH is 6.8-7.8. {ECO:0000269|PubMed:18495639};
CC -!- INTERACTION:
CC F4I907; Q9LPR8: SCL3; NbExp=3; IntAct=EBI-4453651, EBI-4429250;
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast stroma
CC {ECO:0000305|PubMed:18495639}.
CC -!- INDUCTION: By cold and heat stresses. Down-regulated by ozone.
CC {ECO:0000269|PubMed:18495640, ECO:0000269|PubMed:19453511}.
CC -!- MISCELLANEOUS: Although GLYR2 acts as an aldo/keto reductase, it has no
CC significant homology with either mammalian and bacterial NADPH-
CC dependent SSA reductases.
CC -!- SIMILARITY: Belongs to the HIBADH-related family. NP60 subfamily.
CC {ECO:0000305}.
