Cyclic AMP-dependent protein kinase from Ustilago maydis

Molecular and Cellular Biochemistry, 1984
Ustilago maydis was surveyed for cyclic AMP-dependent protein kinase activity. Using a combination of ion-exchange and molecular filtration techniques, we demonstrate that there is only one form of cyclic AMP-dependent protein kinase in the cytosolic fraction of the fungus.

Reversible inhibition of cyclic AMP-dependent protein kinase by insulin

Molecular and Cellular Biochemistry, 1978
Extracts of fasted rat diaphragms, previously treated with or without insulin were assayed for glycogen synthase, protein kinase and cyclic [3H]-AMP binding. Treatment with insulin produced an elevation in the % of glycogen synthase I and a concurrent decrease in cyclic AMP-dependent protein kinase activity and cyclic [3H]-AMP binding.

Inactivation of phosphofructokinase 2 by cyclic AMP-dependent protein kinase

Biochemical and Biophysical Research Communications, 1981
Abstract Treatment with the catalytic subunit of cyclic AMP-dependent protein kinase induced the following modifications in the kinetic properties of purified phosphofructokinase 2. The affinity for Fru-6-P, the Vmax and the stimulatory effect of Pi were decreased; the inhibitory actions of P-enol-pyruvate and citrate were increased; the pH activity ...

Cyclic AMP-dependent protein kinases of bovine epididymal spermatozoa

Biochemical and Biophysical Research Communications, 1972
Abstract Cyclic AMP-dependent protein kinase (cAMP-PrK) activity, some 100-fold greater than that in extracts of other bovine tissues, has been found in sonicates of bovine epididymal spermatozoa. A less than 20-fold purification of the enzyme yields a preparation migrating as three components, two of which possess protein kinase activity, by ...

Cyclic AMP-dependent protein kinase in calf-snout epidermis

Archives of Dermatological Research, 1986
The biochemical characteristics of cyclic AMP-dependent protein kinase in calf-snout epidermis were investigated. The activity of cyclic AMP-dependent protein kinase was higher in the lower layer than the upper layer of epidermis. The supernatant of homogenates of the lower layer of calf-snout epidermis was fractionated by DEAE-cellulose chromatography

Cyclic AMP, cyclic AMP-dependent protein kinase, and the regulation of gene expression

Life Sciences, 1977
Abstract Biological responses produced by cAMP in mammalian cells are remarkably diverse and differ profoundly from one cell type and tissue to another. However, it is thought at this time that all effects of cAMP are mediated through the activation of cAMP-dependent protein kinases.

An unusual cyclic AMP-dependent protein kinase from nematodes

Biochemical and Biophysical Research Communications, 1984
The search for an unusual cyclic nucleotide-dependent protein kinase in nematodes represented an attempt to gain some insight into the proposed homology of the cAMP and cGMP-dependent protein kinases. Two species of protein kinase were found in high speed supernatants of the mycophagous nematode Aphelenchus avenae.

Comparison of substrate specificity of myosin kinase and cyclic AMP-dependent protein kinase

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1984
A series of synthetic peptides corresponding to the amino-terminal region of chicken gizzard myosin light chain (Mr 20 000) have been tested for their capacity to act as substrates for the cAMP-dependent protein kinase. The 18-residue peptide, K6AKTTK11 K12R13PQRATS19NVFS , was stoichiometrically phosphorylated on serine-19 by the cAMP-dependent ...

Identification of Cyclic AMP-Dependent Protein Kinase Activity in Acanthamoeba

Clinical Infectious Diseases, 1991

Cyclic AMP-Dependent and Cyclic GMP-Dependent Protein Kinases of Nervous Tissue

1981
Publisher Summary This chapter focuses on cyclic AMP (cAMP)-dependent and cyclic GMP (cGMP) -dependent protein kinases of nervous tissue. Information about cAMP-dependent and cGMP-dependent protein kinases of brain has increased considerably over the last few years. It is now fairly well established that two types of cAMP-dependent protein kinase and
