Figure 4.

Conservation analysis of the Skp family of proteins. (A) Surface representation of one Skp protomer displaying the degree of evolutionary conservation in a color gradient from dark purple-white-gray, as indicated (47,48). The protomer is shown as part of the Skp trimer (PDB 1SG2 (24)), as well as rotated by 180°. (B) Close-up of Skp in ribbon representation with a highly conserved arrangement of amino acid residues shown as ball and sticks. (C) Amino acid sequence of E. coli Skp with the same coloring. For G57 (yellow), no conservation score could be calculated. The complete alignment is shown in Fig. S1. To see this figure in color, go online.
