Thermodynamic Analysis Reveals a Temperature-dependent Change in the Catalytic Mechanism of Bacillus stearothermophilus Tyrosyl-tRNA Synthetase

Catalysis of tRNA(Tyr) aminoacylation by tyrosyl-tRNA synthetase can be divided into two steps. In the first step, tyrosine is activated by ATP to form the tyrosyl-adenylate intermediate. In the second step, the tyrosyl moiety is transferred to the 3′ end of tRNA. To investigate the roles that entha...
