Inter-monomer interactions in the bacteriophage T5 L-shaped fibre trimer. (A) Side view of the C-terminal fibre domain, with the residues contributing to the central hydrophobic core shown in yellow and labelled on the right; (B) Top view of A, illustrating how the aromatic and hydrophobic residues contribute to the core; (C) Central interactions in the chaperone domain. Hydrophobic side-chains are shown in yellow and other residues in the same colour as the protein chain they belong to.
