LKR — Cucumis sativus

Summary

CsLKR (CSA_1G598330) on cucumber chromosome 1 encodes a protein with saccharopine dehydrogenase (NADP+, L-lysine-forming) activity, belonging to the AASS and LOR/SDH bifunctional enzyme conserved domain superfamily. The gene is associated with L-lysine breakdown, anaerobic respiration, fermentation, TCA cycle, and NO storage, and its product localises to mitochondria and cytosol. It is linked to soluble protein content, protein content, and respiration rate. Related genes in other species are associated with lysine catabolism, seed germination, plant growth, drought recovery, salt tolerance, ABA sensitivity, and mitochondrial function.
