Information contained in protein shapesThe sequence of local conformations at C-alpha atoms of a protein has been considered as an informational message string. The total self-information contents and self-information per letter have been evaluated for 83 globular proteins whose structures are known from X-ray crystallography. The derived information contents provide a method of quantitating structural specificity of proteins. This method of analysis enables repeating, intricate structural features to be recognized. Among the globular proteins whose structures have been solved, high potential iron protein stands out with the largest three-letter dependence.
