Figure 6From: Structural and phylogenetic analysis of a conserved actinobacteria-specific protein (ASP1; SCO1997) from Streptomyces coelicolorHighly conserved regions within the ASP1 trimer. (A) Conserved residues important for forming the central pore and elbow regions. A circle delineates each region. Absolutely conserved residues are colored in purple and highly conserved ones are colored in yellow. (B) and (C) Stereo views of the central pore region and C-terminal elbow regions, respectively. Conserved residues are indicated as in (A). Magnesium ions are shown as black spheres with their first hydration shell of water molecules shown as red spheres.Back to article page
