Influence of proline residues on protein conformation

J Mol Biol. 1991 Mar 20;218(2):397-412. doi: 10.1016/0022-2836(91)90721-h.


To study the influence of proline residues on three-dimensional structure, an analysis has been made of all proline residues and their local conformations extracted from the Brookhaven Protein Data bank. We have considered the conformation of the proline itself, the relative occurrence of cis and trans peptides preceding proline residues, the influence of proline on the conformation of the preceding residue and the conformations of various proline patterns (Pro-Pro, Pro-X-Pro, etc.). The results highlight the unique role of proline in determining local conformation.
