ATPase-promoting dead end inhibitors of the cAMP-dependent protein kinase.
The cAMP-dependent protein kinase is a bifunctional enzyme, catalyzing the phosphorylation of the serine and threonine residues in peptides and proteins (kinase activity) as well as the phosphorylation of water (ATPase activity). We have found that several peptides, which serve as inhibitors of the kinase reaction, will either maintain or enhance the ATPase reaction catalyzed by the enzyme. Pos...
متن کاملTHE 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 phosphorylates and activates nuclear Ca2+-ATPase.
A Ca2+-pump ATPase, similar to that in the endoplasmic reticulum, has been located on the outer membrane of rat liver nuclei. The effect of cAMP-dependent protein kinase (PKA) on nuclear Ca2+-ATPase (NCA) was studied by using purified rat liver nuclei. Treatment of isolated nuclei with the catalytic unit of PKA resulted in the phosphorylation of a 105-kDa band that was recognized by antibodies ...
