UniProtKB - Q9LCX2 (GATB_THET8)
Protein
Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase subunit B
Gene
gatB
Organism
Thermus thermophilus (strain HB8 / ATCC 27634 / DSM 579)
Status
Functioni
Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl-tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp-tRNA(Asn) or phospho-Glu-tRNA(Gln).
Catalytic activityi
- ATP + H2O + L-glutamine + L-glutamyl-tRNAGln = ADP + H+ + L-glutamate + L-glutaminyl-tRNAGln + phosphateUniRule annotation
- ATP + H2O + L-aspartyl-tRNAAsn + L-glutamine = ADP + 2 H+ + L-asparaginyl-tRNAAsn + L-glutamate + phosphateUniRule annotation
