Tertiary core rearrangements in a tight binding transfer RNA aptamer.

Nature structural biology - 1 Jun 2000

Bullock T L, Sherlin L D, Perona J J

Abstract excerpt

Guided by an in vitro selection experiment designed to obtain tight binding aptamers of Escherichia coli glutamine specific tRNA (tRNAGln) for glutaminyl-tRNA synthetase (GlnRS), we have engineered a tRNA mutant in which the five-nucleotide variable loop sequence 5'-44CAUUC48-3' is replaced by 5'-44AGGU48-3'. This mutant tRNA binds to GlnRS with 30-fold improved affinity compared to the wild type. The 2.7 A...
