Fig. 2. Comparison of the AcoP fold with those from other cupredoxins and copper-loading chaperones. (A) Diversity of a region coloured in green (residues 90–128 in AcoP) among the superfamily of cupredoxins: AcoP (PDB: 7Z3B), Azurin (1E5Y), Pseudoazurin (1PZA) or Cucumber Basic Protein (2CBP). (B) Comparison of the non-conserved region (coloured in green) found in AcoP, with regions from copper-bound metallochaperones such as PCuAC from Thermus thermophilus (2K70), and human Sco1 from (2GQM).
