The occurrence of phosphorylated proteins in ribosomes of Streptomyces coelicolor was investigated. Little is known about which biological functions these posttranslational modifications might fulfil. A protein kinase associated with ribosomes phosphorylated six ribosomal proteins of the small subunit (S3, S4, S12, S13, S14 and S18) and seven ribosomal proteins of the large subunit (L2, L3, L7/L12, L16, L17, L23 and L27). The ribosomal proteins were phosphorylated mainly on the Ser/Thr residues. Phosphorylation of the ribosomal proteins influences ribosomal subunits association. Ribosomes with phosphorylated proteins were used to examine poly (U) translation activity. Phosphorylation induced about 50 percent decrease in polyphenylalanine synthesis
