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.
在非洲绿猴肾细胞中生长的传染性猿猴病毒40的所有五种结构多肽都被发现发生了磷酸化。分子量最大和最小的多肽的磷酸化程度略低于其他多肽。基本上不含脱氧核糖核酸的“空”病毒的蛋白质部分表现出与传染性病毒相似的磷酸化程度。在主要多肽(分子量:49,000)中,磷酸盐似乎与丝氨酰或苏氨酰残基结合,或与两者都结合。其他病毒多肽中磷酸 - 多肽键的性质仍不清楚。
