cAMP-dependent protein kinase activity in yeast mitochondria.
Two different cAMP-binding proteins have been identified in yeast mitochondria by photoaffinity labelling and based on the occurrence of cAMP-binding activity in two different sub-mitochondrial fractions. One protein (Mr 45-46,000) is tightly bound to the inner mitochondrial membrane whereas the other (Mr 42,000) is found in the soluble intermembrane space. With endogenous substrate cAMP-depend...
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 کاملDietary modulation of rat colonic cAMP-dependent protein kinase activity.
Malignant transformation of cells is associated with enhanced proliferation and alterations in cAMP-dependent protein kinase (PKA) activity. To investigate the role of PKA in normal colonic cell proliferation, PKA was characterized in rat colonic mucosa. In addition, rats were fed diets containing different fats (corn oil, fish oil) and fibers (pectin, cellulose, fiber free) to elicit varying l...
متن کاملRegulation of cAMP-dependent protein kinase activity by glutathionylation.
The catalytic subunit of cAMP-dependent protein kinase (cAPK) is susceptible to inactivation by a number of thiol-modifying reagents. Inactivation occurs through modification of cysteine 199, which is located near the active site. Because cysteine 199 is reactive at physiological pH, and modification of this site inhibits activity, we hypothesized that cAPK is a likely target for regulation by ...
