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.
