By conditionally depleting lagging-strand nucleases and directly analyzing Okazaki fragments synthesized in vivo in Saccharomyces cerevisiae, we conduct a systematic evaluation of the impact of Rad27, Dna2 and Exo1 on lagging-strand synthesis. We find that Rad27 processes the majority of lagging-strand flaps, with a significant additional contribution from Exo1 but not from Dna2.
Title: Processing of eukaryotic Okazaki fragments by redundant nucleases can be uncoupled from ongoing DNA replication in vivo.
Overexpression of RAD27 impairs DNA replication leading to S phase delay, DNA damage and mutation in a manner that is dependent on its interaction with PCNA.

Data show that unlike short-flap substrates, which are bound, bent and cleaved within the first encounter between Flap Endonuclease 1 (FEN1) and DNA, long-flap substrates can escape cleavage even after DNA binding and bending.
Title: Missed cleavage opportunities by FEN1 lead to Okazaki fragment maturation via the long-flap pathway.
