Class: XopAT
Family: XopAT
Prototype: XCR_1464a (Xanthomonas campestris pv. raphani; strain 756C)
GenBank ID: AEL06363.1 (211 aa)
RefSeq ID: WP_148263049.1 (155 aa, probably too short)
3D structure: Unknown

xopAT was predicted as a novel type 3 effector (T3E) gene because of four criteria (Bogdanove et al., 2011):

1. The gene is encoded next to the hrp gene cluster.
2. The gene contains a plant-inducible promoter (PIP) box and a properly positioned 􏰃10 box-like sequence upstream of the coding sequence.
3. Like other T3E genes, xopAT has an unusual (low) G􏰅+C content suggestive of acquisition by horizontal gene transfer.
4. In common with other T3Es, the encoded protein contains eukaryotic motifs for myristoylation and palmitoylation.

Yes (X. arboricola, X. campestris, X. codiaei, X. cucurbitae, X. fragariae, X. hortorum)

No
