title: In vitro synthesis of tRNA precursors and their conversion to mature size tRNA.
abstract: Two Escherichia coli tRNA gene clusters, tRNA1Tyr (su3+ and su3-) and tRNA2Tyr, tRNA2Gly (su+36), tRNA3Thr, were transcribed in a purified in vitro system. Evidence indicates that the adjacent tRNA genes are transcribed together as a common precursor of large size, which, on incubation with crude cell extracts, yields mature tRNA molecules.
