pHRS7-Histidyl-tRNA Synthetase (E.coli)

This plasmid expresses the full length E. coli Histidyl-tRNA synthetase.

Histidyl-tRNA synthetases attach amino acids to the 3' ends of their cognate transfer RNAs in a two-step reaction catalyzed by ATP. The accuracy of this reaction is crucial for the overall fidelity of protein synthesis.
