CD ComputaBio offers a spectrum of services tailored to protein multipoint mutation design:
Services
Description
Mutational Landscape Analysis
We identify and evaluate the effects of multiple individual mutations across a protein sequence to understand how each possible mutation influences protein function. Using computational algorithms, we can predict which combinations of mutations will yield the desired enhancement or modification of protein activity.
Stability and Solubility Analysis
We analyze how multiple mutations impact the overall stability and solubility of the protein. This service involves molecular dynamics simulations and modeling to predict how different mutation combinations will affect the folding and solubility properties of the protein under physiological conditions.
Functional Optimization
Our team uses advanced computational tools to design proteins with optimized functionalities by introducing multiple mutations. From improving binding affinities to modifying enzymatic activities, we tailor our design strategy to meet your specified functional goals.
Predictive Modeling and Simulation
We deploy sophisticated predictive modeling to simulate the behavior and characteristics of proteins with multiple point mutations. This includes molecular docking, virtual screening, and dynamic simulations to evaluate how mutations will affect protein interactions and in vivo functionality.
Our Algorithm
Computational Saturation Mutagenesis
In this approach, we perform exhaustive in silico mutagenesis across the protein sequence to explore a wide landscape of potential mutations. This helps identify the top candidates for combinatorial mutations by predicting their individual and collective effects on protein function and stability.
Sequence-Based Design
Sequence-based design relies on the analysis of protein sequences to identify conserved regions and amino acid residues that are important for protein function. By mutating these conserved residues, we can potentially improve protein properties while maintaining its overall structure and function.
Machine Learning-Based Design
Machine learning-based design uses machine learning algorithms to predict the effects of mutations on protein properties. By training the algorithms on a large dataset of protein sequences and properties, we can predict the likely effects of mutations on new proteins and design proteins with optimal properties.
