Transition-state stabilization in the mechanism of tyrosyl-tRNA synthetase revealed by protein engineering.
The principal catalytic factor in the activation of tyrosine by the tyrosyl-tRNA synthetase is found to be improved binding of ATP in the transition state. The activation reaction involves the attack of the tyrosyl carboxylate on the alpha-phosphate group of ATP to generate a pentacoordinate transit...
