Abstract
Abstract 6-(3-methyl-2-butenylamino)-2-methylthio-9-(β-D-ribofuranosyl)purine (1) is a naturally occurring nucleoside with potent cytokinin activity. It has been isolated and identified in the t-RNA of E. coli,1,2 the t-RNA from wheat germ3,4 and from Staphylococcus epidermidis.5 In addition, compound 1 has been found in t-RNA species corresponding to each of six amino acids whose codons start with uridine, i.e., t-RNACys
