MDH — Pisum sativum

Summary

PSAT4G028680 (MDH) on garden pea chromosome 4LG4 encodes a protein with a lactate dehydrogenase/glycolate oxidase C-terminal domain and NAD-L-malate dehydrogenase activity. The gene is associated with the TCA cycle, oxidative phosphorylation, cellular respiration, malate metabolism, the glyoxylate cycle, electron transport chain, pentose-phosphate shunt, fermentation, and detoxification. It is linked to sucrose and starch anabolism, stomatal opening, seed germination, regeneration, proteolysis, response to hydrogen peroxide, and NO storage. The product localizes to the mitochondrial lumen and cytoplasm. Studies of related genes in other species link the family to malate dehydrogenase (EC 1.1.1.37) activity. The gene is also associated with germination rate.
