LipidSite lipid binding-site analysis

Lipid binding sites from MD simulations

LipidSite is a Python package for analysing lipid-protein interactions from molecular dynamics (MD) simulations of membrane proteins. It is optimised for Martini 3 coarse-grained simulations of GPCRs with built-in support for active and inactive state classification, but also works with other membrane-protein systems and force fields including atomistic.
