Abstract

32P-labeled, late simian virus 40-specific RNA was isoalted from infected CV1 cells and completely degraded with RNase T2 and bacterial alkaline phosphatase. The RNase-resistant material was fractionated two dimensionally and further characterized with Penicillium nuclease and nucleotide pyrophosphatase. Two major 5' termini were identified in late simian virus 40 RNA, namely, 7-methyl Gppp 2',6-dimethyl ApUp and 7-methyl Gppp 2',6-dimethyl Ap 2'-methyl, UpUp. Both 5' termini are present in unfractionated viral RNA as well as in the separated 16S and 19S species. As both caps differ only in secondary modification, it is possible that they are derived from the same site on the DNA. The relatively higher cap II content of the 16S mRNA may be related to its slower rate of turnover.
