Research Abstract

In this project, we revealed that amino acid motifs critical for substrate specificity of Staphylococcus aureus exfoliative toxin B(ETB) may be located between amino acid residues of 65-232. This project also revealed that two S. pseudintermedius ETs selectively digest canine desmoglein 1, a cell-cell adhesion molecule in canine epidermis.
