>cd00807 Gln_GluRS_non_core Glutaminyl-tRNA synthetase (GlnRS) and non-descriminating Glutamyl-tRNA synthetase (GluRS) cataytic core domain. These enzymes attach Gln or Glu, respectively, to the appropriate tRNA. Like other class I tRNA synthetases, they aminoacylate the 2'-OH of the nucleotide at the 3' end of the tRNA. The core domain is based on the Rossman fold and is responsible for the ATP-dependent formation of the enzyme bound aminoacyl-adenylate. It contains the characteristic class I HIGH and KMSKS motifs, which are involved in ATP binding. These enzymes function as monomers. Archaea and most bacteria lack GlnRS. In these organisms, the "non-descriminating" form of GluRS aminoacylates both tRNA(Glu) and tRNA(Gln) with Glu, which is converted to Gln when appropriate by a transamidation enzyme.
