NON-DISCRIMINATING GLUTAMYL-TRNA SYNTHETASE FROM THERMOSYNECHOCOCCUS ELONGATUS IN COMPLEX WITH GLU
Overview
Error-free protein biosynthesis is dependent on the reliable charging of, each tRNA with its cognate amino acid. Many bacteria, however, lack a, glutaminyl-tRNA synthetase. In these organisms, tRNA(Gln) is initially, mischarged with glutamate by a non-discriminating glutamyl-tRNA synthetase, (ND-GluRS). This enzyme thus charges both tRNA(Glu) and tRNA(Gln) with, glutamate. Discriminating GluRS (D-GluRS), found in some bacteria and all, eukaryotes, exclusively generates Glu-tRNA(Glu). Here we present the first, crystal structure of a non-discriminating GluRS from Thermosynechococcus, elongatus (ND-GluRS(Tel)) in complex with glutamate at a resolution of, 2.45 A. Structurally, the enzyme shares the overall architecture of the, discriminating GluRS from Thermus thermophilus (D-GluRS(Tth)). ... [(full description)]
