Aim. To elaborate the method of expression and purification of bacteria Enterococcus faecalis tRNAPro transcript. Methods. tRNA, co-expressed in vitro with cis-hydrolytical ribozyme, was purified by high performance liquid chromatography using anion-exchange chromatographic column. Results. A satisfactory yield of high purity preparation was obtained. A transcript of tRNAPro exhibits acceptor activity in aminoacylation reaction. Conclusions. The method developed may be introduced in laboratory practice including the obtaining of other tRNAs.
