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

FEATURES

FAMILY

DESCRIPTION

Also known as GATB_JANMA, gatB. 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). Heterotrimer of A, B and C subunits.
