Protein
Malate dehydrogenase 1, mitochondrial
Organism
Arabidopsis thaliana
Function
Catalyzes a reversible NAD-dependent dehydrogenase reaction involved in central metabolism and redox homeostasis between organelle compartments (Probable). Required for carbon dioxide and energy partitioning in leaves. May limit photorespiration during the dark phase (PubMed:20876337, PubMed:27208265). Its activity is essential to shuttle reductants out from the mitochondria to support the photorespiratory flux (PubMed:26889011). Can convert 2-oxoglutarate to (S)-2-hydroxyglutarate in vitro (PubMed:26203119).
Similarity
Belongs to the LDH/MDH superfamily. MDH type 1 family.
