  3. This domain coloring scheme is adapted from Fig. 6 in the review by Lewis (C. R. Biol. 328:521, 2005). Domains are 1-45, 46-62, (63-162,291-320), (163-290,321-332), 330-339, and 340-357.
  4. Conservation results for 1lbg are from the precalculated ConSurf Database, using 103 sequences from Swiss-Prot with an average pairwise distance of 2.4.
  5. Conservation results for 1lbi are from the ConSurf Server, using 100 sequences from Uniprot with an average pairwise distance of 1.3.
  6. 6.0 6.1 For these scenes, the 20-model PDB files for 1osl and 1l1m were reduced in size, to avoid exceeding the java memory available to the Jmol applet. All atoms except amino acid alpha carbons and DNA phosphorus atoms were removed using the free program alphac.exe from PDBTools. Secondary structure HELIX records from the original PDB file header were retained. The results are Image:1osl ca.pdb and Image:1l1m ca.pdb.
