Abstract:
PyInteraph is a software package designed for the analysis of structural communication from conformational ensembles, such as those derived from in silico simulations, under the formalism of protein structure networks. We demonstrate its usage for the calculation and analysis of intramolecular interaction networks derived from three different types of interactions, as well as with a more general protocol based on distances between centers of mass. We use the xPyder PyMOL plug-in to visualize such networks on the three-dimensional structure of the protein. We showcase our protocol on a molecular dynamics trajectory of the Cyclophilin A wild-type enzyme, a well-studied protein in which different allosteric mechanisms have been investigated.
