Abstract
A method for predicting type I and II ?-turns using nuclear magnetic resonance (NMR) chemical shifts is proposed. Isolated ?-turn chemical-shift data were collected from 1,798 protein chains. One-dimensional statistical analyses on chemical-shift data of three classes ?-turn (type I, II, and VIII) showed different distributions at four positions, (i) to (i*+*3). Considering the central two residues of type I ?-turns, the mean values of C?, C?, HN, and NH chemical shifts were generally (i*+*1)*>*(i*+*2). The mean values of C? and H? chemical shifts were (i*+*1)*
