 === How discovered? ===
+XopAY was originally assigned to [[https://www.ncbi.nlm.nih.gov/protein/AAY50220.1|XC_3176]], a protein that was identified as a type 3 effector (see below; Yang //et al.//, 2015). The N-terminal portion of [[https://www.ncbi.nlm.nih.gov/protein/AAY50220.1|XC_3176]] is similar to [[https://www.ncbi.nlm.nih.gov/protein/CAJ22828.1|XCV1197]] and the C-terminal portion is similar to [[https://www.ncbi.nlm.nih.gov/protein/CAJ22829.1|XCV1198]]. [[https://www.ncbi.nlm.nih.gov/protein/CAJ22828.1|XCV1197]] was shown to contain a type 3 secretion signal and was called [[:bacteria:t3e:xopav|XopAV]], now classified as XopAV1 (Teper //et al.//, 2016 ), whereas [[https://www.ncbi.nlm.nih.gov/protein/AAY50220.1|XC_3176]] was classified as XopAV2.

 === (Experimental) evidence for being a T3E ===
+The promoter and signal region of XC_3176 were fused to the HR-inducing AvrBs1 C-terminal domain lack of 58 N-terminal amino acid residues. This construct elicited an hypersensitive response on the pepper ECW-10R containing the corresponding resistance gene //Bs1// in a //hrcV//-dependent manner (Yang et al., 2015).
 === Regulation ===
+A reporter GUS fusion of XC_3176 displayed GUS activities, which were significantly lower in the mutant strains Δ//hrpX// and Δ//hrpG// than that in the wild type //X. campestris// pv. //campestris// strain (Yang et al., 2015).
 === Phenotypes ===
+XC_3176 was found to be required for the full virulence of //X. campestris// pv. //campestris// strain 8004 when assayed on Chinese radish by the leaf-clipping method (Yang et al., 2015).
 === Localization ===
+Unknown
 === Enzymatic function ===
+Unknown
 === Interaction partners ===
+Unknown
 ===== Conservation =====
 === In xanthomonads ===
+Yes (e.g. //X. campestris//, //X. hortorum//, //X. arboricola//, //X. fragariae//)
 === In other plant pathogens/symbionts ===
+No
