Abstract: Protein kinase A (PKA) activity was measured in situ in permeabilised Saccharomyces cerevisiae cells in the absence and the presence of cAMP. Four strains genetically predicted to have differential PKA-dependent phenotypes were used: a wild-type strain and a strain containing a bcy1-14 mutation (with almost constitutively active PKA), and the same strains with overexpression of the wild-type or mutant BCY1 gene, respectively. Cells were grown on galactose or glucose. The measured phenotypic characteristics were: trehalose and glycogen levels and the activity of a reporter gene under control of the NTH1 promoter. The 'endogenous' PKA activity (measured in situ in the absence of cAMP) showed the best correlation with the PKA-dependent phenotypes determined in vivo. We propose that this parameter offers a good estimate for the degree of activation of PKA in vivo. (C) 2002 Federation of European Microbiological Societies. Published by Elsevier Science B.V.
