Protein attributes

Sequence length	500 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	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) By similarity. HAMAP-Rule MF_00121
Catalytic activity	ATP + L-glutamyl-tRNA(Gln) + L-glutamine = ADP + phosphate + L-glutaminyl-tRNA(Gln) + L-glutamate. HAMAP-Rule MF_00121 ATP + L-aspartyl-tRNA(Asn) + L-glutamine = ADP + phosphate + L-asparaginyl-tRNA(Asn) + L-glutamate. HAMAP-Rule MF_00121
Subunit structure	Heterotrimer of A, B and C subunits By similarity.
Sequence similarities	Belongs to the GatB/GatE family. GatB subfamily.
