  ABSTRACT  
 
The human Dmc1 protein, a RecA/Rad51 homolog, is a meiosis-specific DNA recombinase that catalyzes homologous pairing. RecA and Rad51 form helical filaments, while Dmc1 forms an octameric ring. In the present study, we crystallized the full-length human Dmc1 protein and solved the structure of the Dmc1 octameric ring. The monomeric structure of the Dmc1 protein closely resembled those of the human and archaeal Rad51 proteins. In addition to the polymerization motif that was previously identified in the Rad51 proteins, we found another hydrogen bonding interaction at the polymer interface, which could explain why Dmc1 forms stable octameric rings instead of helical filaments. Mutagenesis studies identified the inner and outer basic patches that are important for homologous pairing. The inner patch binds both single-stranded and double-stranded DNAs, while the outer one binds single-stranded DNA. Based on these results, we propose a model for the interaction of the Dmc1 rings with DNA.

Figure 5. The DNA Binding Sites of Dmc1(A) The dsDNA passes through the central channel of Dmc1. The same side chains as in Figure 3C are shown. (B) Double ring formation by Dmc1. (C) Electrostatic surface potential of the Dmc1 double ring structure, viewed from the side. Positively charged cavities are boxed in (B) and (C), and contain an amino acid residue (R311) essential for ssDNA binding. 		Figure 6.
Figure 6. A Model of a Homologous Pairing Intermediate Complex between Dmc1, ssDNA, and dsDNA(A) Schematic representation of dsDNA passing through the central channel of Dmc1. The N-terminal domain (colored yellow) may initially bind to dsDNA, creating a bending stress that could cause the dissociation of the ATPase domain (colored pink).(B) Ternary complex formation by the Dmc1 double ring, ssDNA, and dsDNA requires ATP. The search and the pairing of two homologous sequences could take place at the center of the Dmc1 double ring. The dsDNA is shown entering from one end of the stacked ring. The ssDNA is shown passing through the cavity created by the stacking of two Dmc1 rings.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
