BCCP — Brassica napus

Summary

BnBCCP (DARMORV10_C02P08300.1) on chromosome C02 of oilseed rape encodes a biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, containing biotin-binding and lipoyl domains. The enzyme has acetyl-CoA carboxylase activity and biotin binding. This gene is associated with fatty acid and triglyceride anabolism, lipid storage and metabolism, seed and embryo development, and circadian rhythm. It localises to the plastid, chloroplast stroma and envelope, and the ACCase complex. Associations include chlorophyll content, oil and fatty acid accumulation, pollen and embryo development, and plant growth. Studies of related genes in other species link the family to acetyl-coenzyme A carboxylase activity and embryo lethality.
