Binding of Regulatory Subunits of Cyclic AMP-Dependent Protein Kinase to Cyclic CMP Agarose
The bacterial adenylyl cyclase toxins CyaA from Bordetella pertussis and edema factor from Bacillus anthracis as well as soluble guanylyl cyclase α(1)β(1) synthesize the cyclic pyrimidine nucleotide cCMP. These data raise the question to which effector proteins cCMP binds. Recently, we reported that cCMP activates the regulatory subunits RIα and RIIα of cAMP-dependent protein kinase. In this st...
متن کاملTAYLOR kinase regulatory and catalytic subunits of cyclic AMP - dependent protein
Two classes of molecules inhibit the catalytic subunit (C) of the cyclic AMP-dependent protein kinase (cAPK), the heat-stable protein kinase inhibitors (PKIs) and the regulatory (R) subunits. Basic sites on C, previously identified as important for R/C interaction in yeast TPKI and corresponding to Lys213, Lys217, and Lys189 in murine Ca, were replaced with either Ala or Thr and characterized f...
متن کاملCyclic AMP- and (Rp)-cAMPS-induced conformational changes in a complex of the catalytic and regulatory (RI{alpha}) subunits of cyclic AMP-dependent protein kinase.
We took a discovery approach to explore the actions of cAMP and two of its analogs, one a cAMP mimic ((S(p))-adenosine cyclic 3':5'-monophosphorothioate ((S(p))-cAMPS)) and the other a diastereoisomeric antagonist ((R(p))-cAMPS), on a model system of the type Iα cyclic AMP-dependent protein kinase holoenzyme, RIα(91-244)·C-subunit, by using fluorescence spectroscopy and amide H/(2)H exchange ma...
متن کاملActivation of type I cyclic AMP-dependent protein kinases with defective cyclic AMP-binding sites.
Two S49 mouse lymphoma cell variants hemizygous for expression of mutant regulatory (R) subunits of type I cyclic AMP-dependent protein kinase were used to investigate functional consequences of lesions in the putative cAMP-binding sites of R subunit. Kinase activation properties of wild-type and mutant enzymes were compared using cAMP and six site-selective analogs of cAMP. Kinases from both m...
متن کاملby cyclic AMP-dependent protein kinase
Myosin light-chain kinase was purifed from bovine carotid artery. Approx. 90% of myosin kinase was extracted in the supernatant fraction with buffer containing EDTA during myofibril preparation. The soluble fraction yielded two distinct peaks on DEAE-Sephacel chromatography. Peak I was eluted at a conductance of 11-12mmho and was completely dependent on Ca2+-calmodulin for its activity. Peak II...
