Polyclone’s In silico Enzyme Engineering Framework (eEF) is a smart integration of proprietary algorithms and processes for high throughput and high confidence predictions of enzyme & protein modifications for desired properties. The solution integrates computational library design, directed evolution and statistical modeling of sequence–function relationships while considering the intermediary stages of enzyme-substrate interaction to achieve its goals.

eEF
The enzyme engineering framework
  • Provides enzyme models at process conditions, for a combination of desired physical and catalytic properties (like altered thermal/pH stability, increased activity) thus saving on costs and time
  • Adopts an approach comparable to in vitro biochemical studies and ensures biologically relevant predictions with a high confidence level (≥ 70%)
  • Employs built-in ranking functions to capture the finer details of intermolecular interactions and energetics across enzyme-substrate reaction, to provide a list of prioritized results based on the application
  • Enables understanding of the intricacies of enzyme-substrate interaction at the atomic level and helps in introducing novel modifications to the enzyme which may otherwise not have been discovered
