Abstract
By phenol extraction and DEAE cellulose column chromatography, tRNA was isolated from Tetrahymena pyriformis strain GL. Following acid hydrolysis of the tRNA, the methylated purine content was determined by Dowex 50 column chromatography and paper chromatography. The most abundant methylated guanine derivative was found to be N2-DMG. Also present were 1-MG, N2-MG, and 7-MG. The most abundant methylated adenine was found to be 1-MA; no 2-MA was detected. Small amounts of the N6-methyladenines were detected.Entities:
