Figure 3From: Comparative void-volume analysis of psychrophilic and mesophilic enzymes: Structural bioinformatics of psychrophilic enzymes reveals sources of core flexibilityDifference in frequency of each amino acid type on the inner cavity surface between psychrophilic and the mesophilic paired proteins. Psychrophilic enzymes have a larger number of acidic side chains on the inner surface of a cavity (p < 0.01). Mesophilic enzymes have a larger number of hydrophobic residues (p < 0.01).Back to article page
