Central core of the bacterial effector protein AvrPto

This family of proteins represents the bacterial effector protein AvrPto from Pseudomonas syringae. This is the central core region of the protein which consists of a three-helix bundle motif. AvrPto is part of a type III secretion system from P.syringae which is involved in the bacterial speck disease of tomato. In resistant plants, AvrPto interacts with the host Pto kinase, which elicits an antibacterial defense response. In plants lacking resistance, the Pto kinase is not present and AvrPto acts as a virulence factor, promoting bacterial growth.
