LKR — Brassica napus

Summary

BnLKR (LKR) on chromosome C01 of oilseed rape (Brassica napus) encodes a bifunctional enzyme with saccharopine dehydrogenase (NADP+, L-lysine-forming) activity, belonging to the LOR/SDH bifunctional enzyme conserved domain family. The gene is associated with L-lysine breakdown and the TCA cycle, and its product localises to mitochondria and the cytosol. Studies of the Arabidopsis relative link the family to lysine catabolism, mitochondrial function, seed germination, and stress responses including salt and osmotic stress tolerance. Sequence similarity connections further associate the family with drought recovery, chlorophyll content, plant height, root length, and seed growth and development traits.
