Biological function

How discovered?

XopW was discovered via genome-wide screening for effector candidates in X. oryzae pv. oryzae (Xoo) strain MAFF 311018 in accordance with three criteria: i) ORF encoding proteins homologous to effectors of P. syringae strains and X. campestris pv. vesicatoria, ii) HrpX regulons preceded by two cis elements (Plant Induced Promoter, PIP; and -10 box-like motif) or iii) proteins with an N-terminal amino acid composition similar to known effectors (more than 10% of Ser in the first 50 amino aa, no Asp or Glu residues in the first 12 aa, and an aliphatic amino acid or Pro at the third or fourth position) (Furutani et al., 2009).

(Experimental) evidence for being a T3E

TT3S-dependent translocation of XopW has been shown by a calmodulin-dependent adenylate cyclase reporter assay (Furutani et al., 2009).
