Information about secondary structures and sequence alignment of (a) HptB and (b) PA1611REC with structural homologues obtained using the DALI server. The sequence comparison was performed with the ESPript web server (https://espript.ibcp.fr/ESPript/ESPript/). The residues with high similarity appear in blue boxes; the conserved residues are white shaded in red. The species and PDB codes of each protein sequence are as follows: ZmHP2, Zea mays, 1wn0 (Sugawara et al., 2005); Hpt domain of ArcB, Escherichia coli, 2a0b (Kato et al., 1999b); MtHPt1, Medicago truncatula, 3us6 (Ruszkowski et al., 2013); YPD1, Saccharomyces cerevisiae, 2r25 (Zhao et al., 2008); AHP1, Arabidopsis thaliana, 4euk (Bauer et al., 2013); RR468, Thermotoga maritima, 3gl9 (Casino et al., 2009); VcCheY4, Vibrio cholerae, 4h60 (Biswas et al., 2013); CtrAREC, Brucella abortus, 4qpj (Willet et al., 2015); RR02rec, Streptococcus pneumoniae, 1nxw (Bent et al., 2004); PhoB REC, Escherichia coli, 1b00 (Sola et al., 1999); BfmRN, Acinetobacter baumannii, 6br7 (Draughn et al., 2018). |
