title: Synthesis and circular dichroism studies of two polypeptides H-[Gly-(Pro)3]n-OH and H-[Gly-(Pro)4]n-OH.
abstract: Recently Gly-(Pro)3 a proline-rich protein (PRP) containing repetitive Gly-(Pro)3 or Gly-(Pro)4 sequences was isolated from human parotid saliva. The synthesis of two polypeptides containing these sequences is described. Their circular dichroism spectra have been recorded and are compared with the circular dichroism spectrum of the natural protein.
