Accordingly, a progressive clockwise axial rotation can account for the structural transition from a protein ring (PDB accession code: 1PZN) to a right-handed RadA-AMP-PNP filament with six monomers p... r helical turn (PDB accession code: 1T4G), then to an overextended right-handed filament with three monomers per helical turn (PDB accession code: 2Z43), and, finally, to a left-handed filament with four monomers per helical turn (PDB accession code: 2DFL).
To further illustrate the structural flexibility between the NTD and the CAD, we compared 11 different RadA and Rad51 monomeric structures (i.e., 1PZN, 1T4G, 2Z43, 2DFL, 2ZUB_A, 2ZUC_A, 2ZUD_A, 2ZUB_B, 2ZUC_B, 2ZUD_B and 1SZP) by fixing their PMs and the neighboring α5 helix ( Figure 4 ) and also by comparing their Φ and Ψ angles as described previously  ( Table 2 ).

Similar assemblies of PfRadA and HsDMC1 Interestingly, the crystal packing of heptameric PfRadA (Shin et al. , 2003 ▶ ; PDB entry 1pzn ) and octameric HsDMC1 (Kinebuchi et al. , 2004... ▶ ; PDB entry 1v5w ) suggests that they both form similar two-ringed assemblies with D 7 and D 8 point-group symmetry (Figs. 2 b ▶ and 2 c ▶ ), respectively.

However, when we examined the crystal packing of classical recombinases RecA (3CMT) ( 47 ), PfRad51 (1PZN) ( 48 ) and RadA (3NTU), we observed dimers with a conformation similar to our top–bot... om ICP8 dimers fitted into one symmetrical unit of the density map.

The region of the Schellman loop appears to be important in archaeal Rad51 orthologs as well, since the structure of Pyrococcus furiosus RadA protein (PDB ID: 1PZN) ( 44 ) reveals a modified Schellman... loop motif in which a mini-helix containing two Glu residues is separated from α-helix 1 by an extra Pro residue (Figure 1A ).
