Detailed view of the hydrogen bond pattern, in the Pro-kink turn, of model peptides containing the P(S/T), PA(S/T), and PAA(S/T) patterns, with Ser and Thr side chains built in both g+ and g− conformations. Only polar hydrogens are depicted to offer a better view. The OγH group of Ser/Thr is interacting with the carbonyl oxygen at position j-4, relative to Ser/Thr, except when noted.
