The Sak protein from phage 80alpha shares similarities with other SSAPs, such as Red-beta from phage alpha and RAD52 from eukaryotes. SSAPs like Sak play a crucial role in homologous recombination by promoting the annealing of complementary single-stranded DNA. Sak adopts a similar to other SSAPs structure and shows the groove commonly seen in SSAPs to accommodate ssDNA in the outer surface of the torus, known as the ssDNA binding groove or ssDBG [1].
