Comparison of CdAlr with selected representative Alrs. The amino-acid sequence alignment of representative Alrs showing structural elements of CdAlr and EcAlr was generated with ESPript3.0 (Gouet et al., 2003 ). Secondary-structure elements are as follows: α-helices are shown as large coils labeled α, 310-helices are shown as small coils labeled η, β-strands are shown as arrows labeled β and β-turns are labeled TT. Identical residues are shown on a red background, conserved residues are shown in red and conserved regions are shown in blue boxes. The representative Alrs are the homologs from G. stearothermophilus (GsAlr; PDB entry 1xqk; Fenn et al., 2005 ), B. anthracis (BaAlr; PDB entry 3ha1; Couñago et al., 2009 ), S. lavendulae (SlaAlr; PDB entry 1vft; Noda et al., 2004 ), S. aureus (SaAlr; PDB entry 4a3q; Scaletti et al., 2012 ), M. tuberculosis (MtbAlr; PDB entry 1xfc; LeMagueres et al., 2005 ) and E. coli (EcAlr; PDB entry 2rjg; Wu et al., 2008 ). |
