additional information | construction of a chimeric glutamyl:glutaminyl-tRNA synthetase, cGluGlnRS, consisting of the catalytic domain of the GluRS and the anti-codon binding domain of the GlnRS. The chimeric mutant shows detectable glutamylation activity with Escherichia coli tRNAGlu and is capable of complementing a ts-GluRS strain at non-permissive temperatures. The GlnRS anticodon-binding domain in cGluGlnRS enhances kcat for glutamylation, interaction analysis, overview | Escherichia coli |
