-  * Experimental evidence using heterologous expression of //avrXccB//  suggests that this protein is involved in the suppression of plant immunity. Immunity suppression in //Arabidopsis//  involved multiple mechanisms: ectopic expression of //avrXccB//  reduced flg22-induced callose deposition and ROS production, while //avrXccB//  expression in //Arabidopsis//  protoplasts inhibited the promoter activity of resistance gene //NHO1//. Heterologous expression of //avrXccB//  led to an increase in the in-planta population of //Xcc//  B186 and //Pst//  DC300 in //Arabidopsis//. Conversely, //avrXccB//  mutants were compromised in their ability to inhibit MAMP-induced immunity (callose deposition, ROS production and defence-related genes in //Arabidopsis//  protoplasts) (Liu //et al//., 2017).

 === Localization ===
-Plant plasma membrane, confirmed experimentally through GFP-tagged AvrXccB expression in transgenic //Arabidopsis//. The putative //N//  ‐myristoylation motif is essential for its localization (Thieme //et al//., 2007; Liu //et al//., 2017).

 === Enzymatic function ===
-Cysteine protease/acetyltransferase (putative) (Liu //et al//., 2017). Point mutations in the catalytic triad (conserved with other YopJ-like proteins which also function as protease/acetyltransferases) compromised //NOH1//  promoter activity and were deprived of their abilities to suppress flg22-induced callose deposition and ROS production (Liu //et al//., 2017).
