Responses to arsenate stress by Comamonas sp. strain CNB-1 at genetic and proteomic levels, by Y. Zhang, Y.-F. Ma, S.-W. Qi, B. Meng, M. T. Chaudhry, S.-Q. Liu and S.-J. Liu

Microbiology vol. 153, part 11, pp. 3713 - 3721

Fig. S1. Phylogenetic analysis of functionally identified (shown in bold) and putative prokaryotic arsenate reductases. The phylogenetic tree was generated using the neighbour-joining method with the Mega 4.0 software. The scale at the bottom shows sequence divergence. Numbers at nodes show the support from 1000 bootstraps. The eukaryotic arsenate reductases from Saccharomyces spp. were used as outgroup. [PDF] (75 kb)

Fig. S2. Comparative proteomes of Comamonas sp. strain CNB-1 grown in the presence (top) and the absence (bottom) of arsenate. CNB-1 was cultured in LB broth with and without 100 mM sodium arsenate for 24 h. 2-DE was performed using different pH gradient strips (pH 4-7 and pH 6-11). Numbered proteins were differentially expressed under arsenate stress, and their identities are listed in Table 2 of the main paper. The proteins that showed increased abundance or only appeared in the presence of arsenate are marked with solid arrows (upper panels), and the proteins that showed increased abundance or only appeared in the absence of arsenate are marked with open arrows (lower panels).

Fig. S3. Global responses to arsenate exposure in Comamonas sp. strain CNB-1. Up-regulated proteins are marked with triangles; induced proteins are marked with squares. For further explanation of the figure, see the main paper. [PDF] (66 kb)
