[https://www.uniprot.org/uniprot/RADA_METVO RADA_METVO] Involved in DNA repair and in homologous recombination. Binds and assemble on single-stranded DNA to form a nucleoprotein filament. Hydrolyzes ATP in a ssDNA-dependent manner and promotes DNA strand exchange between homologous DNA molecules (By similarity). | |||

== Publication Abstract from PubMed == | |||
Archaeal RadAs are close homologues of eukaryal Rad51s ( approximately 40% sequence identities). These recombinases promote a hallmark strand exchange process between homologous single-stranded and double-stranded DNA substrates. This DNA-repairing function also plays a key role in cancer cells' resistance to chemo- and radiotherapy. Inhibition of the strand exchange process may render cancer cells more susceptible to therapeutic treatment. We found that metatungstate is a potent inhibitor of RadA from Methanococcus voltae. The tungsten cluster binds RadA in the axial DNA-binding groove. This polyanionic species appears to inhibit RadA by locking the protein in its inactive conformation. | |||
