Structural Proteins of Simian Virus 40: Phosphoproteins

K B Tan 1, F Sokol 1
PMCID: PMC356569  PMID: 4344258

Abstract

All five structural polypeptides of infectious simian virus 40 grown in African green monkey kidney cells were found to be phosphorylated. The polypeptides with the largest and smallest molecular weights are phosphorylated to a somewhat lower extent than the other polypeptides. The protein moiety of “empty” virus, which is essentially devoid of deoxyribonucleic acid, exhibited a degree of phosphorylation similar to that of infectious virus. In the major polypeptide (molecular weight: 49,000), the phosphate appears to be bound to the seryl or threonyl residues, or both. The nature of the phosphate-polypeptide bond in the other viral polypeptides remains obscure.
