Abstract excerpt
One surprising outcome of applying the techniques of protein engineering to the enzyme tyrosyl-transfer RNA synthetase was that the enzyme's activity could actually be increased by a specific sequence change. In particular, altering residue threonine 51 to a proline (mutant TP51) increased the enzyme's affinity for tyrosyl adenylate complexes. The non-additive effect of combining the TP51 mutation with a second...
