title: beta sheet formation by L-methionine oligopeptides.
abstract: Monodispersed N- and C-protected linear homo-oligomethionines (n = 2- -7) are studied by measurements of circular dichroism in the vacuum ultraviolet region. In the solid state higher members of the series take up a beta-conformation in which both parallel and antiparallel chain arrangements are present. The strong beta-forming tendency of the methionine residue is demonstrated.
