Dihedral angles analysis and Ramachandran Plots #10
Description
Biopython has a method that allows the measurement of dihedral angels. Dihedral angles are formed by 4 atoms connected by three covalent bonds, and with the middle covalent bond capable of rotating. We would like to measure all the dihedral bonds in a protein and output them for further analysis. Ramachandran plots are the most famous plots obtained from dihedral angle analysis (see http://mordred.bioc.cam.ac.uk/~rapper/rampage.php). These plots are used mostly to understand protein folding, but they could be useful to have a very concise way to see the conformational freedom of the linker for open insulin. There is a multitude of dihedral angle analysis tools and methods on line. We could use a third party software to get this, but if we cannot find a solution that meets our needs, developing a set of tools to analyse these dihedral angles inside Entropy Maxima is necessary.
