GatB_N

GatB_N
PFAM accession number:PF02934
Interpro abstract (IPR006075):

Glutamyl-tRNA(Gln) amidotransferase subunit B (EC 6.3.5) [(PUBMED:9342321)] is a microbial enzyme that furnishes a means for formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln). The enzyme is composed of three subunits: A (an amidase), B and C. It also exists in eukaryotes as a protein targeted to the mitochondria.

GO function:ligase activity (GO:0016874)
