Abstract excerpt
Among the twenty aminoacyl-tRNA synthetases glutaminyl-tRNA synthetase occupies a special position: it is one of only two enzymes of this family which is not found in all organisms, being mainly absent from gram positive eubacteria, archaebacteria and organelles. The E. coli GlnRS is relatively small with 553 amino acids and a molecular mass of 64.4 kDa and functions as a monomer. The mammalian enzymes are...
