Solvent accessibilities of Cys residues introduced to the 11 different positions of VSD from S3b to S4.
(a) Gel shift assay of VSD. The number of the residue, to which Cys was introduced, was indicated. (b) Mapping of the results. Highly PEGylated residues, which possess high solvent-accessibility, are colored red whereas others are cyan on the structure of VSD (PDB code 2KYH).
