ACCEPTOR STEM, NMR, 30 STRUCTURES
Overview
The fidelity of translation of the genetic code depends on accurate tRNA, aminoacylation by cognate aminoacyl-tRNA synthetases. Thus, each tRNA has, specificity not only for codon recognition, but also for amino acid, identity; this aminoacylation specificity is referred to as tRNA identity., The primary determinant of the acceptor identity of Escherichia coli, tRNAAlais a wobble G3.U70 pair within the acceptor stem. Despite extensive, biochemical and genetic data, the mechanism by which the G3.U70 pair marks, the acceptor end of tRNAAla for aminoacylation with alanine has not been, clarified at the molecular level. The solution structure of a microhelix, derived from the tRNAAla acceptor end has been determined at high, precision using a very extensive set of experimental constraints, ... [(full description)]
