Figure 3
Sequence alignment of the tetrahedral motifs. The zinc-binding motifs of human ZnTs and bacterial CDF members are shown. The alignment was prepared using MUSCLE (Edgar, 2004) and Jalview (Waterhouse et al., 2009). The tetrahedral motif is mostly highlighted in blue. Red highlighting indicates the different residues in the two CDF proteins associated with Mn2+ transport. Yellow and grey highlighting indicates residues that differ from the standard (D or H) residues in the tetrahedral motif. TM, transmembrane. Accession numbers are as follows: Escherichia coli YiiP (EcYiiP), P69380; Shewanella oneidensis YiiP (SoYiiP), Q8E919; Thermus thermophilus CzrB (TtCzrB), Q8VLX7; ZnT1, Q9Y6M5; ZnT2, Q9BRI3-2; ZnT3, Q99726; ZnT4, O14863; ZnT5, Q8TAD4; ZnT6, Q6NXT4; ZnT7, Q8NEW0; ZnT8, Q8IWU4; ZnT9, Q6PML9; ZnT10, Q6XR72; Streptococcus pneumoniae MntE (SpMntE), Q8DP19; S. pneumoniae CzcD (SpCzcD), A0A0B7LW62. |
