Phylogeny of cation diffusion facilitators in Frankia. Neighbor-joining tree of Frankia proteins containing the cation diffusion facilitator (CDF) domain (pfam01545). CDFs used for comparison include the characterized ZnT-9 from Homo sapiens (SLC30A9), iron (FieF) and zinc (ZitB) CDFs from E. coli K12-W3110, and CDFs up-regulated in the compiled array data (underlined) (see Additional file 1). CDFs of S. viridochromogenes and B. subtilis subtilis 168, which were used for specific metal resistance comparison in Richards et. al. 2002, were also included. Metals that are up-regulated-specific proteins are displayed on their branches. In locus tags: * = DRAFT, ** = 0101000. The following three types of CDF and identifying regular expression amino acid motifs are shown (“.” indicates any single amino acid, and “.*” indicates unspecified number of amino acids): A. CzcD: [QE]........S.....D..H…[DH].*[ST][FWY].{2,3}[RK].*H…D.*[DE].H, B. FieF: [FY]G[HY].[RK].E.*D…[SN].....[GA].*R..G.*..P, C. ZnT-9: N......K.*HS..D..N.*ED.{24,24}[FWD][ED].
