Notes:
tRNA containing N6-(Δ2-isopentenyl)adenosine may be precursors for the plant hormone cytokinin. To discriminate between tRNA containing and not containing cytokinin nucleotides, double labelling experiments were made by the use of [214C]-mevalonic acid and [3H-methyl]-methionine. At a generation cycle of 2 h for Lactobacillus acidophilus ATCC 4963, the half-lives of tRNA labelled with [3H-methyl]-methionine and [2-14C]-mevalonic acid are similar, namely 3 h. Isopentenylation of tRNA could be measured to be maximally 1:10.
