Comparative structural analysis of AP in different organisms. (A) Sequence comparison of PhoA^aty among different organisms and the section containing four conserved domains (adapted from Moore et al., 2005 and Scanlan et al., 2009). Representative sequence labeled with “asterisk” indicated this gene has been characterized partially. (B) WebLogo showing the consensus of amino acid sequences acquired from the alignment of four conserved domains (detail alignment shown in Supplementary Figure 2).
