This domain, approximately 140 residues in length, is mainly found in general stress proteins in various Xanthomonas species. It is composed of a six-stranded antiparallel beta-barrel flanked by five alpha-helices and can bind to FMN and FAD, suggesting that it may help the bacteria to react against the oxidative stress induced by the defense mechanisms of the plant [1].
