  • Title: Phosphorylation of proteolytically-nicked rat hepatic acetyl-CoA carboxylase.
    Author: Gillevet PM, Dakashinamurti K.
    Journal: Int J Biochem; 1983; 15(11):1361-5. PubMed ID: 6139304.
    Abstract:
    A partially-purified preparation of acetyl-CoA carboxylase was not inactivated by ATP and Mg2+ although it was phosphorylated. SDS gel electrophoresis of the phosphorylated enzyme showed phosphopeptides migrating at 140 and 40 K along with the 250 K native subunit. Phosphorylation by the catalytic subunit of cAMP-dependent protein kinase further phosphorylated an additional 120 K phosphopeptide. Neither cAMP-independent phosphorylation nor the cAMP-dependent phosphorylation of the enzyme resulted in a significant decrease in activity.
