Abstract: We have analyzed the role of single-stranded DNA (ssDNA) in the modulation of the ATPase activity of Mcm467 helicase of the yeast Saccharomyces cerevisiae. The ATPase activity of the Mcm467 complex is modulated in a sequence-specific manner and that the ssDNA sequences derived from the origin of DNA replication of S. cerevisiae autonomously replicating sequence 1 (ARS1) are the most effective stimulators. Synthetic oligonucleotides, such as oligo(dA) and oligo(dT), also stimulated the ATPase activity of the Mcm467 complex, where oligo(dT) was more effective than oligo(dA). However, the preference of a thymidine stretch appeared unimportant, because with yeast ARS1 derived sequences, the A-rich strand was as effective in stimulating the ATPase activity, as was the T-rich strand. Both of these strands were more effective stimulators than either oligo(dA)( )()or oligo(dT). The DNA helicase activity of Mcm467 complex is also significantly stimulated by the ARS1-derived sequences. These results indicate that the ssDNA sequences containing A and B1 motifs of ARS1, activate the Mcm467 complex and stimulate its ATPase and DNA helicase activities. Our results also indicate that the yeast replication protein A stimulated the ATPase activity of the Mcm467 complex.
