UniProtKB - O27341 (GATB_METTH)
Protein
Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase subunit B
Gene
gatB
Organism
Methanothermobacter thermautotrophicus (strain ATCC 29096 / DSM 1053 / JCM 10044 / NBRC 100330 / Delta H) (Methanobacterium thermoautotrophicum)
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 + phosphate
- ATP + H2O + L-aspartyl-tRNAAsn + L-glutamine = ADP + 2 H+ + L-asparaginyl-tRNAAsn + L-glutamate + phosphate
