Figure 1
Crystal structure of MtHigA3. (a) Front view of the overall MtHigA3 structure. Two monomers of MtHigA3 interact to form a dimer with HTH motifs on either side of the dimer structure, and a β-lid is formed as a result of this dimer organization. Front view of the salt bridge formed between Arg45 and Glu71 (left). Front view (middle) and top view (right) of the hydrophilic interactions between the loop and the adjacent α4-helix are enlarged in the panels. Each monomer, including residues from each chain, is coloured cyan and blue. (b) Topology diagram of the MtHigA3 dimer. The secondary structure elements are coloured the same as in (a).
