CC -!- FUNCTION: Catalyzes a reversible NAD-dependent dehydrogenase reaction
CC involved in central metabolism and redox homeostasis between organelle
CC compartments (Probable). Peroxisomal NAD-dependent malate dehydrogenase
CC involved in fatty acid beta-oxidation. Reoxidizes NADH from the beta-
CC oxidation and provides NAD for the conversion of fatty acyl-CoA to
CC acetyl-CoA. Does not participate directly in the glyoxylate cycle
CC (PubMed:17376163, PubMed:19812894). Required for maintenance of
CC photosynthetic rates under photorespiratory conditions, and carbon flow
CC during photorespiration. Supplies NADH reductant to the peroxisomal
CC hydroxypyruvate reductase (HPR), which reduces hydroxypyruvate into
CC glycerate in the photorespiratory cycle (PubMed:18685043).
CC {ECO:0000269|PubMed:17376163, ECO:0000269|PubMed:18685043,
CC ECO:0000269|PubMed:19812894, ECO:0000305|PubMed:20876337}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(S)-malate + NAD(+) = H(+) + NADH + oxaloacetate;
CC Xref=Rhea:RHEA:21432, ChEBI:CHEBI:15378, ChEBI:CHEBI:15589,
CC ChEBI:CHEBI:16452, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=1.1.1.37;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10004};
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Peroxisome {ECO:0000269|PubMed:17376163}.
CC -!- TISSUE SPECIFICITY: Expressed in rosette leaves at low levels.
CC {ECO:0000269|PubMed:20876337}.
CC -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC conditions, but the double mutant plants pmdh1 and pmdh2 show seedling
CC growth arrest 5 days after seed imbibition.
CC {ECO:0000269|PubMed:17376163}.
CC -!- SIMILARITY: Belongs to the LDH/MDH superfamily. MDH type 1 family.
CC {ECO:0000305}.
