- ProteinGlutamyl-tRNA(Gln) amidotransferase subunit B, chloroplastic/mitochondrial
- GeneGATB
- StatusUniProtKB reviewed (Swiss-Prot)
- Amino acids562 (go to sequence)
- Protein existenceInferred from homology
- Annotation score3/5
Function
function
Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in chloroplasts and mitochondria. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln).
Miscellaneous
This protein may be expected to contain an N-terminal transit peptide but none has been predicted.
Catalytic activity
- ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H+ + L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate
