Designer Enzymes and Proteins mimicking evolution on a laboratory timescale can be used to modulate and optimize challenging bimolecular properties such as activity, selectivity, stability, resistance to proteolytic degradation, solubility, etc,. Engineering enzymes and turning them into molecular machineries for producing pharmaceutical product is a billion dollar market. Therefore, the understanding of enzyme-substrate (E-S) relationship and studying the thermodynamics of protein folding is critical for both drug discovery, development and in their production. Rational redesign and directed evolution approach are the two major ways of exploring new properties of a given biomolecule. These approaches are time and resource consuming, shown to produce higher failure rate than success rate, sometimes becomes an iterative process without reasoning. To intervene with greater impact at this point is the use of computational biology which is used not only to predict novel properties of biomolecules but also as a tool to reason and explore the atomic level details responsible for a specific change. The pitfalls of using computational tools are mainly due to inappropriate selection of algorithms and even unreasonable use of such techniques would lead to false positive prediction, meaning just by misinterpreting the output of a docking or a simulation experiment, will yield results that repeatedly fail to deliver in the lab. Unifying different computational techniques, we have developed a framework and experimented on some commercially important proteins. The in silico framework called as enzyme engineering framework (eEF) used for enzyme/protein engineering is a step beyond the SBDD and virtual screening. The framework works sequentially to identify hot spots in enzymes, generate more than a hundred thousand mutations, filter for the most appropriate E-S mutations and simulate E-S reaction to predict the kinetics, activation energies and rate limiting steps of the potential enzyme/protein mutants.
