Expert reviewer: WANTED!

Class: XopAO
Family: XopAO
Prototype: XGA_1250 (Xanthomonas hortorum pv. gardneri, ex. Xanthomonas gardneri; strain 101 = ATCC 19865)
GenBank ID: EGD20072.1 (206 aa)
RefSeq ID: WP_162267513.1 (207 aa)
3D structure: Unknown

Biological function

How discovered?

XopAO was predicted to be a type 3 effector based on homology to AvrRpm1, a type 3 effector from Pseudomonas syringae (Potnis et al., 2011).

(Experimental) evidence for being a T3E

T3SS-mediated translocation of XopAO was assessed by constructing fusion genes with the C-terminal end of AvrBs2 coding sequence (avrBs2 62-574) in a race 6 strain of X. euvesicatoria. Translocation was measured in pepper cv. ECW 20R, containing the resistance gene Bs2. xopAO was demonstrated to direct AvrBs2-specific hypersensitive reactions in ECW 20R (Potnis et al., 2011).
