Question

10. What principle does tRNA synthetase proofreading work on? Based on the structure of the editing

domain of threonyl-tRNA synthetase from Methanococcus jannaschii with L-Thr3AA (PDB: 4RRG),

which amino acids can be mutated to make this enzyme bad at proofreading? Is entropy a contributor

to the stability of this complex? Why or why not? (4 pts)
