Sequence analyses of XC_0531 of Xanthomonas campestris pv. campestris. a Physical and genetic map of the Xanthomonas campestris pv. campestris dsbD region. The pink arrowhead stands for the dsbD encoding open reading frame XC_0531. The small arrows represent the position of primers used to construct of the 0531pk. b Alignment of amino acid sequence of DsbD homologs from Xanthomonas campestris pv. campestris 8004, Shewanella oneidensis MR-1and Escherichia coli str. K-12. The gene XC_0531 of Xanthomonas campestris pv. campestris, SO_0696 of Shewanella oneidensis MR-1 and b4136 of Escherichia coli str. K-12 were aligned. Navy blue boxes denote identical amino acid residues, whereas baby blue boxes are similar between the two sequences. The starred area denotes the typical redox active -Cys-X-X-Cys- motif of the disulfide bond formation protein family. c Prediction of transmembrane helices of XC_0531 of Xanthomonas campestris pv. campestris. This was analyzed with TMHMM Server v.2.0 software. Red blocks stand for the transmembrane helices in cytoplasmic membrane while pink threads for periplasmic loops and blue for regions inside the cytoplasm
