gatB2

Gene
gatB2
Protein
Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase subunit B 2
Organism
Syntrophus aciditrophicus (strain SB)
Length
476 amino acids
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).
Similarity
Belongs to the GatB/GatE family. GatB subfamily.
Mass
53.532 kDa
