【 摘 要 】

Two types of super-secondary structure, coiled β-β-hairpins and β-β-corners, are considered in this paper. A β-β-corner can be represented as a long β-β-hairpin folded orthogonally on itself so that the strands, when passing from one layer to the other. rotate in a right-handed direction about an imaginary axis. It is shown that a β-β-hairpin. forming a coiled coil structure or a β-β-corner, is right-handed when viewed from the concave side. These unique arrangements of β-strands in the coiled β-β-hairpins and β-β-corners are of particular value in protein modelling and prediction.
