№ - Ramachandran plot evaluation - Standard deviation of omega values 1 - (-2.164) - 6.543 2 - (-2.018) - 6.758 3 - (-1.376) - 6.643 4 - (-2.046) - 6.300 5 - (-2.214) - 6.427 i - (-0.977) - 2.708 The Ramachandran plot is probably the very best indicator of the quality of the experimental determination of three dimesional protein coordinates. This server analyses the Ramachandran plot of a PDB file and compares it with the Ramachandran plots of about 400 representative structures solved at high resolution. The score expressing how well the backbone conformations of all residues correspond to the known allowed areas in the Ramachandran plot is a bit low. The omega angles for trans-peptide bonds in a structure is expected to give a gaussian distribution with the average around +178 degrees, and a standard deviation around 5.5. In the current structure the standard deviation agrees with this expectation.
