Biological Effects of Listeriolysin O: Implications for Vaccination

Figure 1

A structure-function relationship model of Listeriolysin O (LLO). LLO domains are represented in a different color: domain 1 blue, domain 2 yellow, domain 3 green, and domain 4 pink. Key residues or sequences for biological activity or immunogenicity are highlighted in red color. The LLO structure-function model was generated based on the crystal structure reported by Köster et al. [2] with PYMOL program.
