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. |
