The original article [1] contains an omission in the legend of Fig. 2 whereby inadequate credit was given to the authors of the original print of Fig. 2 which was reproduced from the original article published in Medicinal Research Reviews [2].

Fig. 2

The crystal structure of three different classes of PPIs [2]. A) Linear sequences comprise primary peptide epitopes (e.g. LM of DNA polymerase III bound to the binding pocket of the SC (PDB: 3D1F)); B) the secondary structure of epitopes binds as a single unit. e.g. an α-helix (NusB-NusE PPI (PDB: 3R2C)); and C) in tertiary structural epitopes, the binding interface is not continuous and both sides of PPI interface are needed (e.g. IL-2/IL-2Ra PPI (PDB 1Z92))

The correct version of Fig. 2’s legend with appropriate citation can be viewed ahead alongside its respective figure.
