Protein

Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase subunit B

Gene

gatB

Organism
Chlamydia trachomatis serovar A (strain ATCC VR-571B / DSM 19440 / HAR-13)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

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).UniRule annotation

Catalytic activityi

ATP + L-glutamyl-tRNA(Gln) + L-glutamine = ADP + phosphate + L-glutaminyl-tRNA(Gln) + L-glutamate.UniRule annotation
ATP + L-aspartyl-tRNA(Asn) + L-glutamine = ADP + phosphate + L-asparaginyl-tRNA(Asn) + L-glutamate.UniRule annotation
