Figure 3 Detailed views of domains/motifs in DR RecR. (A) HhH
motifs from two monomers are swapped. Gly21, Arg23 and Lys27 are
shown. Primed residues belong to the second subunit B in Figure
2C. (B) Cys[4] zinc-finger motif. (C) Toprim domain with
residues Glu86, Asp90 and Glu146. Corresponding positions (142
and 144) of the 'DxD' sequence are indicated by red balls. (D)
The C-terminal regions from two monomers are swapped. Arg167 and
Asp182 are the fingerprint residues of the canonical Walker B
motif. Double-primed residues belong to the third subunit C. The
orientations of domains/motifs are roughly similar to those in
subunits B (colored in white green), D (purple) and C (white
blue) in Figure 2C.
