Prolyl Oligopeptidase in Physiology and Pathology
Keywords:
proteolytic enzymes, serine peptidase, prolyl oligopeptidase, physiological roleAbstract
Prolyl oligopeptidase is an atypical serine peptidase which digests bioactive peptides, including hormones and neuropeptides. Prolyl oligopeptidase cleaves internal peptide bonds on the C-terminal side of proline residues. Orthologous enzymes are found in plants, bacteria, fungi, protozoa, invertebrates and vertebrates. This review provides an update on function and structure of prolyl oligopeptidase; it is also focused on its biological role and implication in physiological processes and disorders.
