효소의 융합 이성적 설계 (Hybrid Rational Design of Enzymes) |
| 초록 |
The large number of mutant library in protein engineering makes the experimental procedure laborious and time consuming. Therefore, we sought to devise a quantitative combinatorial screening approach that would allow rapid probing of residues lying in the outer layer of the active site. Many available methods use molecular mechanics to describe the system. However, molecular mechanics force fields cannot fully describe the complex interactions involved in ligand binding, electron transfer, and polarization. In this study a novel combinatorial method, hybrid rational design including QM/MM-based quantitative screening followed by experimental validation was established. For a proof of concept, several enzymes were chosen to demonstrate the feasibility of hybrid rational design as a platform tool in protein engineering. We describe the screening and characterization of highly active mutants using hybrid rational design based on free energy of activation (△G‡). The promising outcome of the hybrid rational design provides new avenues for future research aimed at engineering of any enzymes. |
