Phosphorylation of endogenous protein of rat brain by cyclic adenosine 3',5'-monophosphate-dependent protein kinase.
The ability of proteins in various subcellular fractions of the rat cerebrum to act as substrates for a partially purified cyclic adenosine 3’,5’-monophosphate (cyclic AMP)-dependent protein kinase has been studied in vitro. Distribution of substrates generally paralleled the distribution of activity of protein kinase as well as of adenylate cyclase and cyclic nucleotide phosphodiesterase. Alth...
متن کاملAdenosine cyclic 3',5'-monophosphate dependent protein kinase: active site directed inhibition by Cibacron Blue F3GA.
Cibacron Blue F3GA, the polycyclic blue chromophore of Blue Dextran 2000, inhibits the catalytic subunit of bovine brain protein kinase. The rate of inactivation exhibits a hyperbolic dependence on the dye concentration. This suggests that an enzyme-dye complex forms prior to inactivation. Protein and peptide substrates or MgATP protects the enzyme against dye inactivation. Kinetic measurements...
متن کاملFluorometric assay for adenosine 3',5'-cyclic monophosphate-dependent protein kinase and phosphoprotein phosphatase activities.
A novel peptide substrate for adenosine 3',5'-cyclic monophosphate-dependent protein kinase (ATP:protein phosphotransferase, EC 2.7.1.37), Leu-Arg-Arg-Trp-Ser-Leu-Gly, was synthesized. Phosphorylation of the peptide causes a 20% increase in the peptide fluorescence intensity at 358 nm. Values of Km and kcat for the phosphorylation reaction at pH 7.0 (25 degrees C), were determined to be 2.7 +/-...
متن کاملAdenosine cyclic 3',5'-monophosphate dependent protein kinase: nucleotide binding to the chemically modified catalytic subunit.
5'-[p-(Fluorosulfonyl)benzoyl]adenosine (FSBA) inactivates the catalytic subunit of the adenosine cyclic 3',5'-monophosphate dependent protein kinase isolated from bovine cardiac muscle by covalent modification of lysine-71, whereas 7-chloro-4-nitro-2,1,3-benzoxadiazole (NBD-Cl) and 5,5'-dithiobis(2-nitrobenzoic acid) (DTNB) react with cysteines-199 and -343 to inactivate the enzyme. All three ...
متن کاملDevelopment of a peptide inhibitor-based cantilever sensor assay for cyclic adenosine monophosphate-dependent protein kinase.
A highly sensitive nanomechanical cantilever sensor assay based on an electrical measurement has been developed for detecting activated cyclic adenosine monophosphate (cyclic AMP)-dependent protein kinase (PKA). Employing a peptide derived from the heat-stable protein kinase inhibitor (PKI), a magnetic bead system was first selected as a vehicle to immobilize the PKI-(5-24) peptide for capturin...
