The use of double mutants to detect structural changes in the active site of the tyrosyl-tRNA synthetase (Bacillus stearothermophilus)
In a previous study, a mutant of tyrosyl-tRNA synthetase in which a threonine residue
(Thr51) was converted to proline dramatically improved the aff inity of the enzyme for its ATP …
