Glutaminyl-tRNA synthetase, non-specific RNA binding region part 1
This is a region found N terminal to the catalytic domain of glutaminyl-tRNA synthetase (EC 6.1.1.18) in eukaryotes but not in Escherichia coli. This region is thought to bind RNA in a non-specific manner, enhancing interactions between the tRNA and enzyme, but is not essential for enzyme function.
