The phosphorylation of an acidic protein of the large ribosomal subunit of Krebs II ascites cells.
The ribosomes of Krebs II ascites cells contain an acidic protein, apparently analogous to proteins L7/12 of Escherichia coli. When ascites cells were incubated with [32P]Pi, this protein became labelled, indicating that it is a phosphoprotein.
