Low activity of the yeast cAMP-dependent protein kinase catalytic subunit Tpk3 is due to the poor expression of the TPK3 gene.

European journal of biochemistry - 1 Apr 1993

Abstract excerpt

Three genes TPK1, TPK2 and TPK3 encode in Saccharomyces cerevisiae distinct catalytic subunits of cAMP-dependent protein kinase (cAPK). We have measured cAPK activity in vitro and, indirectly, in vivo in yeast strains carrying only one of the three TPK genes. The strain containing TPK3 as the only intact TPK gene showed nearly undetectable phosphorylating activity and no TPK3 mRNA could be detected, although the...
