Antibody structure prediction / Conformational ensembles / Descriptor calculations / Property prediction / Developability / Cloud computing

Predicting potential liabilities such as aggregation or viscosity is a key step in monoclonal antibody development. Computational property prediction methods are routinely used in the selection and optimization of candidate antibodies. High-quality property prediction involves prediction of ensembles of 3D structures at specified pH to reduce sensitivity to single conformational states. We will present 3dpredict/Ab, a solution that enables ensemble-based predictions of antibody developability descriptors and putative liabilities. 3dpredict/Ab allows for out-of-the-box SaaS automation and integration of such complex simulations of hundreds or thousands of sequences, making them accessible and efficient.

The webinar covers methods for analyzing and optimizing peptide-protein interactions in the active site. Using a model system consisting of MDMX protein and a peptide ligand modelled from p53, key contacts and interactions will be identified. Properties of the peptide ligand will be calculated, and opportunities for optimisation of the peptide will be derived by calculating protein patches and other properties for the receptor. We will then see how to mutate the residues in the peptide ligand to optimise binding, both by editing one residue at a time, and by "residue scanning" / virtual mutagenesis, which allows us to investigate the effects of multiple mutations together, thereby identifying beneficial changes.
