title: Bases methylated in vitro by cell-free extracts of adenovirus-18-induced tumours.
abstract: The tRNA methylase activity in vitro of adenovirus-18-induced tumour was studied. The activity expressed per mg of protein was the same for extracts of tumours induced by either adenovirus-12 or adenovirus-18. The methylated bases isolated after incubation with extract from adenovirus-18-induced tumour were N(1)-methylguanine, 1-methyladenine, 3-methyladenine and N(6)-methyladenine.
