Atomic coordinates in the Worldwide Protein Data Bank (wwPDB) are generally reported to greater precision than the experimental structure determinations have actually achieved. By using information theory & data compression to study the compressibility of protein atomic coordinates, it is possible to quantify the amount of randomness in the coordinate data & thereby to determine the realistic precision of the reported coordinates. On avg., the value of each C_alpha coordinate in a set of selected p.structures solved at a variety of resolutions is good to about 0.1A.
