 ===== Biological function =====
 === How discovered? ===
-XopE4 was first identified by sequence homology searches (Moreira //et al//., 2010).
+XopE4 was first identified by sequence homology searches (Moreira //et al//., 2010).
 === (Experimental) evidence for being a T3E ===
 Homology to other XopE effectors.
 === Regulation ===
 Unknown.
 === Phenotypes ===
-The gene sequence of xopE4 is similar to avrXopE3, but due to its low amino acid sequence identity (31%) was considered a different effector that can discriminate between X. citri and //X. fuscans// pv. aurantifolii strains, both causing citrus bacterial canker (Moreira //et al//., 2010; Dalio //et al//., 2017). Disease symptoms caused //Xanthomonas axonopodis// pv. manihotis mutant strains on //xopE4// are similar to those caused by the wild-type strain. Moreover, using heterologous systems XopE4 was demonstrated unable to suppress (PAMP)-triggered immunity (PTI) but showed the ability to suppress effector-triggered immunity (ETI) (Medina //et al//., 2018).

Moreover, using heterologous systems XopE4 was unable to suppress (PAMP)-triggered immunity (PTI) but showed weak ability to suppress effector-triggered immunity (ETI) (Medina //et al//., 2018).
 === Localization ===
-As XopE4 does not have a predicted myristoylation site, suggesting that it may not be targeted to the cell membrane as the other XopE family member (Moreira //et al//., 2010).

 === Enzymatic function ===
