Abstract
A super-secondary structural motif comprising two orthogonally oriented β-strands connected by short linking segments of ≤5 residues has been identified from a data set of 65 independent protein crystal structures. Of the 42 examples from 14 proteins, a vast majority have only a single residue as the linking element. Analysis of the conformational angles at the junction reveals that the recently described type VIII β-turn occurs frequently at the connecting hinge, while the type II β-turn is also fairly common.
