Reversible phosphorylation of acidic ribosomal proteins of Saccharomyces cerevisiae is an important mechanism, regulating the number of active ribosomes. The key role in regulation of this process is played by specific, second messenger-independent protein kinases. A new protein-inhibitor regulating activity of PK60S kinase has been purified from yeast extracts and characterised. Peptide mass fingerprinting (PMF) and amino-acid sequence analysis by Post Source Decay (PSD) have identified the… CONTINUE READING
