Viewing an Evolutionary Trace with PyMOL and the PyETV plugin

Summary: PyETV is a PyMOL-based graphical user interface for viewing, analyzing and manipulating functional site predictions on protein tertiary or quaternary structures. Starting from the Evolutionary Trace (ET) server output, namely ranks of relative functional importance for every amino acid in a protein, PyETV maps these rankings onto the structures of the chains of a complex. This provides a convenient, high quality graphics platform for viewing evolutionarily important parts of a protein complex, and integrating them with other tools provided by PyMOL in order to guide analysis and bioengineering to the most functionally relevant part of a protein. PyETV is a downloadable PyMOL plugin written in Python.
