BCCP2 — Brassica napus

Summary

BnBCCP2 (BCCP2) on chromosome A10 of oilseed rape encodes a protein with biotin-binding and acetyl-CoA carboxylase activity, and contains domains including AcCoA_biotinCC, Biotin_BS, 2-oxoacid dehydrogenase, Biotin_lipoyl, and Single hybrid motif. The gene is associated with lipid metabolism, lipogenesis, fatty acid anabolism, seed development and growth, embryogenesis, and pyruvate metabolism. It is linked to seed oil content, fatty acid composition and content, seed mass, seed setting, sucrose content, and chlorophyll content. The encoded protein localises to the chloroplast envelope and stroma and the ACCase complex. Studies of related genes in other species connect the family to seed oil deposition, seed carbohydrate content, acetyl-coenzyme A carboxylase activity, and tolerance to salt, alkali stress, and ABA.
