Phys. Rev. E 71, 012901 (2005) [3 pages]Self-similarity and protein chainsReceived 13 January 2004; revised 16 November 2004; published 27 January 2005 Fractal properties of 5526 different protein chains are investigated. Characteristic fractal behavior for different molecular systems is obtained from the fractal dimension analysis, which shows that the dimension is δ=2.47. This dimension gives a measure of the protein compactness. The present finding indicates that the fractal analysis describes some structural properties of proteins and corroborates the explanation about multifractality in the energy hypersurface. © 2005 The American Physical Society URL:
