Sequence tendencies. (a) The solid or dashed line corresponds to [PDB:2LHC] (GA98-1) or [PDB:2LHD] (GB98-1), respectively. (b) The solid or dashed line corresponds to [PDB:2LHG] (GA98-2) or [PDB:2LHE] (GB98-2), respectively. While the x-axis denotes residue number, the y-axis denotes the relative similarity to 2FS1/1PGA. Positive or negative large value means the local sequence has high similarity to [PDB:2FS1] (GA) or [PDB:1PGA] (GB), respectively. The bold numbers represent the residue numbers at peaks or valleys of the plot. How we get the sequence tendencies is described in the Material and Methods section.
