Abstract

This paper provides an introduction to fundamental conformational states of polypeptides in the β-region of φ,ψ space, in which the backbone is extended near to its maximal length, and to more complex architectures in which extended segments are linked by turns and loops. There are several variants on these conformations, and they comprise versatile scaffolds for presentation of side chains and backbone amides for molecular recognition and designed catalysts. In addition, the geometry of these fundamental folds can be readily mimicked in peptidomimetics. © 2005 Wiley Periodicals, Inc. Biopolymers (Pept Sci) 84: 13–22, 2006
