arginyl-tRNA synthetase, MtArgRS, directly and stably interacts with seryl-tRNA synthetase, MtSerRS, EC 6.1.1.11, two-hybrid system and surface plasmon resonance analysis, overview. The MtSerRS-MtArgRS complex also contains tRNAArg, consistent with the existence of a stable ribonucleoprotein complex active in aminoacylation. Deletion of the HTH motif, which contributes to the stability of SerRS dimers, significantly weakens the interaction between the two synthetases. Stimulation by MtArgRS peaks at 65°C |
