J = 1.12 cm-', F ( O O 0 ) = 384, 7 = 291K, R = 0.056 for 717 observed reflections. The (0, 9 ) values of (el", 35'), (-174", 169") and (-79',164') define a left-handed a-helix conformation at Gly(1). an extended form at Gly(2) and a collagen-like conformation at terminal Pro respectively. The pyrrolidine ring has a Cs-C6-ero conformation.
