Figure 2. Structure and sequence characteristics of HK3 β-propeller domains.

Figure 2

(A) Ribbon diagram of the D1 domain of HK3 BT4673S viewing the top side [38]. Strands are colored yellow and loops are green.

(B) Ribbon diagram of the D2 domain of HK3 BT4673S oriented and colored as in A except that two short helices are in red.

(C) Topology diagram of the β-propeller domains.

(D) Superimposition of ribbon diagrams of all 14 propeller blades from HK3 BT4673S.

(E) Stereodiagram showing the interactions between three adjacent propeller blades. Blades 9–11 from D2 of HK3 BT4673S are shown as ribbon diagrams with contact residues drawn in stick representation. Hydrophobic contacts are shown as red dotted lines with the shortest distance labeled.

(F) The structure-based sequence alignment of all 14 blades of HK3 BT4673S.

The ribbon figures were generated using PyMol [69], and the sequence alignment figure was drawn using ESPript [70–72]. Strand and turn residues in blade 1 of D1 are shown as arrows or by T, respectively.
