Gene: hopAB3, hopPmaL (PSEYM) Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function [HPAB3_PSEYM] Effector protein involved in gene-for-gene resistance in tomato plants. It is recognized by the host Pto resistance protein and elicits Pto and Prf-dependent hypersensitive response (HR) and programmed cell death (PCD), resulting in host immunity. In susceptible plants, promotes virulence, in part, by enhancing the development of disease symptoms and bacterial growth. Publication Abstract from PubMed HopPmaL is a member of the HopAB family of type III effectors present in the phytopathogen Pseudomonas syringae. Using both X-ray crystallography and solution nuclear magnetic resonance, we demonstrate that HopPmaL contains two structurally homologous yet functionally distinct domains. The N-terminal domain corresponds to the previously described Pto-binding domain, while the previously uncharacterised C-terminal domain spans residues 308-385. While structurally similar, these domains do not share significant sequence similarity and most importantly demonstrate significant differences in key residues involved in host protein recognition, suggesting that each of them targets a different host protein. Structural Analysis of HopPmaL Reveals the Presence of a Second Adaptor Domain Common to the HopAB Family of Pseudomonas syringae Type III Effectors.,Singer AU, Wu B, Yee A, Houliston S, Xu X, Cui H, Skarina T, Garcia M, Semesi A, Arrowsmith CH, Savchenko A Biochemistry. 2012 Jan 10;51(1):1-3.
