Synthetic tRNA for selenoprotein production is described by D. Söll et al. in their Communication on page 1441 ff. The tRNA is a substrate for three E. coli proteins: seryl-tRNA synthetase (SerRS), selenocysteine synthase (SelA) generating Sec-tRNAUTu, and EF-Tu for Sec-tRNAUTu transport to the ribosome, which allows site-specific Sec insertion into proteins. This system has general utility in protein engineering, molecular biology, and disease research.
