title: Proposed knobs-into-holes packing for several membrane proteins.
abstract: We investigated the possible side chain/side chain interactions of four potential transmembrane proteins. The basic assumptions are that the proteins are alpha-helical, and that the proteins aggregate with knobs-into-holes packing. It was found that these four proteins can be assembled into stereochemically feasible bundles of alpha-helices with hydrophobic exteriors and with hydrogen bonds between the side chains of one alpha-helix and the side chains of its knobs-into-holes packed neighbors.
