Figure 3.
The distribution of candidate fragments for engineering of the native protein G. The distribution of candidate fragments are projected on two coordinates, sequence identity, and hydrophobicity scale difference when their Cα-RMSD is smaller than 2.5 Å. (A) The candidate fragment distribution for building block-I of the native protein G. (B) The candidate fragment distribution for building block-II of the native protein G. Fragments with lower sequence identity and smaller hydrophobicity scale difference are used for engineering protein G.
