 === (Experimental) evidence for being a T3E ===
-XopD is a desumoylating enzyme with strict specificity for its plant small ubiquitin-like modifier (SUMO) substrates (Chosed //et al//., 2007). C-terminus of XopD (amino acids 322–520) shares primary sequence similarity with the C48 family of cysteine peptidases. In the XopD polypeptide, amino acid positions 309–481 are most homologous to the C-terminal catalytic domain of the Ulp1 ubiquitin-like protease protein family, which is highly conserved (Hotson //et al//., 2003; Li & Hochstrasser, 1999). Unlike yeast Ulp1 which process a variety of SUMO substrates, XopD exhibits rigid SUMO substrate specificity, it will process only certain plant SUMOs, //i.e.// T-SUMO, //At//SUMO-1, and //At//SUMO-2 (Chosed //et al//., 2007). However, another study has shoxn that XopD shows a mixed activity, being a (tomato)-SUMO and Ubiquitin isopeptidase. The capacity to efficiently recognize both substrates suggest a large evolutionary pressure to become a multifunctionnal protease (Pruneda //et al//., 2016).

 Besides C-terminal SUMO protease domain (Chosed //et al//., 2007; Hotson //et al//., 2003), XopD has a unique N-terminal region with a host range determining non-specific DNA-binding domain (DBD) (Kim //et al//., 2011) and a central domain with two internal ERF-associated amphiphilic repression (EAR) motifs (L/FDLNL/FXP)(Ohta //et al//., 2001), which were found in plant repressors that regulate stress induced transcription. XopD might repress host transcription during //Xcv// infection (Ohta //et al//., 2001; Kim //et al//., 2011).
