title: Complementary packing of alpha-helices in proteins.
abstract: The packing of alpha-helices in proteins is restricted by both the principle of close packing and the chemical nature of side chains. As a result, (1) alpha-helical surfaces forming the interface should be complementary to each other, (2) hydrophobic stripes of the alpha-helices should fit together like pieces of a jigsaw puzzle, and (3) buried polar side chains (if there are any) should be arranged in a complementary fashion.
