In this work the abilities of plant viral and artificial enhancers of mRNA translation to increase synthesis of sheep pox viral coat proteins A27L and L1R in wheat germ cell-free system is studied and compared. For such a comparison 5' untranslated regions (UTRs) of genomic (g)RNAs of potato virus Y (PVY), tobacco etch virus (TEV), gRNA-4 of alfalfa mosaic virus (AMV), artificial enhancer 5xARC1, as well as 3' UTR of a tobacco mosaic virus (TMV) gRNA were used. The assessment of translation enhancement was made by measurement of activity of newly synthesized reporter protein β-glucuronidase (GUS) that hydrolyzes the fluorogenic substrate, as well as with the help of immunoblotting of proteins A27L and L1R. It is established that examined 5'-UTRs can considerably raise synthesis of proteins in comparison with arbitrary leader sequence (pl), which does not possess translational enhancer property.References
