Figure 1. Amino acid sequence alignment of the four conserved copper-binding sites of MCOs from diverse strains.

Figure 1

The copper-binding regions A, B, C and D correspond to those shown in Figure S1. The copper-binding residues are designated T1, T2, T3a and T3b on the basis of the types of copper which they potentially bind. MnxG, marine Bacillus sp. strain SG-1 MnxG (GenBank accession no. AAB06489.1); MofA, L. discophora SS-1 MofA (GenBank accession no. CAA81037.2); MoxA, Pedomicrobium sp. ACM 3067 MoxA (GenBank accession no. CAJ19378.1); CotA, B. pumilus WH4 CotA (this study, GenBank accession no. AFL56752.1). Conserved amino acids are shaded in black (90% conservation or more) or in grey (70 to 90% conservation).
