>cd00806 TrpRS_core Tryptophanyl-tRNA synthetase (TrpRS) catalytic core domain. TrpRS is a homodimer, which attaches Tyr to the appropriate tRNA. TrpRS is a class I tRNA synthetases, so it aminoacylates 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 class I characteristic HIGH and KMSKS motifs, which are involved in ATP binding
