Another important role of proline residues is their involvement in β turns. β turns are 180° turns commonly found in globular proteins to allow for a compact structure by connecting the ends of adjacent antiparallel β sheets [http://en.wikipedia.org/wiki/Beta_sheet]. The turn consists of a sequence of four amino acid residues. The carbonyl of the first amino acid hydrogen bonds with the amino group of the fourth amino acid. Proline is involved in β turns because it is small and flexible and assumes a ''cis'' conformation. In RNase A both Pro93 and Pro114 are involved in β turns. | Another important role of proline residues is their involvement in β turns. β turns are 180° turns commonly found in globular proteins to allow for a compact structure by connecting the ends of adjacent antiparallel β sheets [http://en.wikipedia.org/wiki/Beta_sheet].
