| Researchers at Purdue University have developed nuclear-magnetic resonance (NMR)-related software for simulation and analysis of protein interactions across multiple states detected with NMR chemical shifts. Proteins can have complex interactions; accordingly, multi-state equilibria involve complex mathematical models with simultaneous equations and matrix manipulations. Nonetheless, most existing tools for fitting NMR line shape data can only support a simple 2-state binding model. The Purdue researchers' software, called NMRLineGuru, simulates and fits NMR line shapes with two-, three-, and four-state binding models. It is a standalone and user-friendly software for simulating and fitting NMR line shapes. In fitting NMR line shape data, the Purdue system accounts for both thermodynamic and kinetic interaction parameters among proteins. Related Publication: Feng, C., Kovrigin, E.L. & Post, C.B.
