Fig. 2. (a) Topology diagram showing the connectivity of secondary structure elements and domain organization of the S. solfataricus KdaD monomer. The N terminus of the polypeptide chain (N, in blue) follows a color gradient towards the C terminus (C, in red). (b and c) Ribbon diagrams at two viewing angles of the KdaD monomer with Mg^2+ and 2-oxobutyrate bound.
