Prereplicative complexes assembled in vitro support origin-dependent and independent DNA replication.
(WILEY-BLACKWELL, 2014-03-18)
Eukaryotic DNA replication initiates from multiple replication origins. To ensure each origin fires just once per cell cycle, initiation is divided into two biochemically discrete steps: the Mcm2-7 helicase is first loaded ...
Structural basis for translocation by AddAB helicase-nuclease and its arrest at χ sites.
(NATURE PUBLISHING GROUP, 2014-04-17)
In bacterial cells, processing of double-stranded DNA breaks for repair by homologous recombination is dependent upon the recombination hotspot sequence χ (Chi) and is catalysed by either an AddAB- or RecBCD-type ...
