Structure of eukaryotic CMG helicase at a replication fork and implications to replisome architecture and origin initiation [Biophysics and Computational Biology]

The eukaryotic CMG (Cdc45, Mcm2–7, GINS) helicase consists of the Mcm2–7 hexameric ring along with five accessory factors. The Mcm2–7 heterohexamer, like other hexameric helicases, is shaped like a ring with two tiers, an N-tier ring composed of the N-terminal domains, and a C-tier of C-terminal domains; the C-tier contains...
