The identity elements of transfer RNA are the molecular basis for recognition by each cognate aminoacyl-tRNA synthetase. In the archaea system, the tryptophan tRNA identity has not been determined in detail. To investigate the molecular recognition mechanism of tryptophan tRNA by tryptophanyl-tRNA synthetase (TrpRS) from the hyperthermophilic and aerobic(More)
Phenylalanine tRNA identity has been determined in the bacteria and the eukaryote system, but remains unknown for the archaea system. To investigate the molecular recognition mechanism of phenylalanine tRNA by phenylalanyl-tRNA synthetase from hyperthermophilic and aerobic archaeon, Aeropyrum pernix K1, various mutant transcripts of phenylalanine tRNA(More)
To investigate the recognition mechanism of tryptophan tRNA by tryptophanyl-tRNA synthetase from extreme hyperthermophilic and aerobic archaeon, Aeropyrum pernix K1, tryptophanylation activities were examined by using mutant tryptophan tRNA transcripts prepared by in vitro transcription system. Their transcripts were aminoacylated with tryptophan by(More)
