THE EFFECT OF THEOPHYLLINE ON THE KINETICS OF cAMP-DEPENDENT PROTEIN KINASE CATALYTIC SUBUNIT, cAMP, PROTEIN KINASE INHIBITOR AND THEIR RELATIONSHIP IN LUNG TISSUE
We have investigated the effect of theophylline on the kinetics of the catalytic subunit of protein kinase and related factors in lung tissue. The results show that the point of highest concentration of the C subunit of protein kinase which is active in casein phosphorylation is at 3h of incubation time, but in the presence of 100 Ilg/ InL and 10µg/mL theophylline, this is shifted to I.S an...

متن کاملcAMP-dependent protein kinase activation lowers hepatocyte cAMP.
Rat hepatocyte protein kinase was activated by incubating the cells with various cAMP analogs. Boiled extracts were then prepared and Sephadex G-25 chromatography was carried out. The G-25 procedure separated the analogs from cAMP since the resin had the unexpected property of binding cyclic nucleotides with differing affinities. Separation was necessary because the analogs would otherwise inte...

متن کاملA constitutively active holoenzyme form of the cAMP-dependent protein kinase.
The major function of the regulatory (R) subunit of the cAMP-dependent protein kinase is to bind tightly to the catalytic (C) subunit to form an inactive holoenzyme in the absence of cAMP. The hinge region of the R subunit resembles the substrate recognition site for the C subunit and is known to be involved in the R.C subunit interaction. Two arginine residues in this region, Arg-92 and Arg-93...
