Fig. 3From: A hydrophobic spine stabilizes a surface-exposed α-helix according to analysis of the solvent-accessible surface areaThe structures of proteins 1MOF (a), 2WRP (b), 1MOF_I54D (c), and 2WRP_H15I (d). The yellow spheres denote the residues constituting the hydrophobic spine. The red spheres are the side chains of hydrophilic residues that interrupt the hydrophobic spine (resulting in an imperfectly hydrophobic spine)Back to article page
