Simulated probability distributions of end-to-end distance. Normalized end-to-end distributions computed for the sequences (a) C(XGX)4W and (b) CX14W, where X represents any amino acid excluded glycine, proline and pre-proline, are reported for hard sphere diameter dα = 0 Å (solid lines), 3 Å (dashed lines), and 5.5 Å (dotted lines). Distributions are generated from 2 (105) accepted conformations and truncated at r = 4 Å.
