Figure 12From: Mechanisms for stabilisation and the maintenance of solubility in proteins from thermophilesSurface adaptation in hyperthermophiles. Numerous surface acidic residues (red) in both hyperthermophile, (a) 1oz9, and mesophile, (b) 1xax, members of a homologue pair, are joined by many more basic residues (blue) in the hyperthermophile representative. (c) The location of tryptophan residues (cyan) in a hyperthermophile protein (pdb id 1zar).Back to article page
