-===== Biological function =====
+===== Acknowledgements =====
-=== How discovered? ===
+This fact sheet is based upon work from COST Action CA16107 EuroXanth, supported by COST (European Cooperation in Science and Technology).
-XopAK was discovered using a machine-learning approach (Teper //et al//., 2016).
-=== (Experimental) evidence for being a T3E ===
-XopAK, fused to the AvrBs2 reporter, was shown to translocate into plant cells in an //hrpF//-dependent manner (Teper //et al//., 2016).
-=== Regulation ===
-Unknown.
-=== Phenotypes ===
-Disease severity, ion leakage, chlorophyll content of pepper plants inoculated with a mutant strain obtained by insertion mutagenesis of //xopAK// and //in planta// bacterial growth were not affected as compared to plants inoculated with the parent strain //X. euvesicatoria// pv. //euvesicatoria// (//Xcv//) 85-10 (Teper //et al//., 2016).
-=== Localization ===
-Unknown.
-=== Enzymatic function ===
-XopAK has been predicted to be a deamidase (Teper //et al//., 2016).
-=== Interaction partners ===
-Unknown.
-===== Conservation =====
-=== In xanthomonads ===
-Yes (//e.g.//, //X. citri, X. euvesicatoria//, //X. oryzae, X. translucens//) (Barak //et al//., 2016; Teper //et al//., 2016)
-=== In other plant pathogens/symbionts ===
-Yes (//e.g.//, //Pseudomonas syringae// effector HopK1, //Ralstonia solanacearum// (Petnicki-Ocwieja //et al.//, 2002; He //et al.//, 2004; Li //et al//., 2014; Schechter //et al.//, 2004; Teper //et al//., 2016)
