- Translocation of Saccharomyces cerevisiae Pif1 helicase monomers on single-stranded DNARoberto Galletto
252 McDonnell Science Building, Department of Biochemistry and Molecular Biophysics, Washington University, School of Medicine, 660 South Euclid Avenue, MS8231, Saint Louis, MO 63110
Nucleic Acids Res 41:4613-27. 2013..Finally, although we show that Pif1 can translocate on ssDNA, the translocation profiles suggest the presence on ssDNA of two populations of Pif1, both able to translocate with 5' to 3' directionality...
- DNA binding induces dimerization of Saccharomyces cerevisiae Pif1Sergio Barranco-Medina
Department of Biochemistry and Molecular Biophysics, Washington University School of Medicine, Saint Louis, Missouri 63110, USA
Biochemistry 49:8445-54. 2010..The observation that a Pif1 dimer is formed on unwinding substrates in the presence of ATP analogues suggests that a dimeric form of the enzyme might constitute the pre-initiation complex leading to its unwinding activity...
