Cryo-EM structures of the eukaryotic replicative helicase bound to a translocation substrate
The Cdc45-MCM-GINS (CMG) helicase unwinds DNA during replication, a process that requires the ATPase-dependent activity of the MCM complex. Using cryo-EM reconstructions of the CMG complex in different conformations, the authors propose a model where the N-terminal and AAA+ domains of MCM work in co...

| Sumario: | The Cdc45-MCM-GINS (CMG) helicase unwinds DNA during replication, a process that requires the ATPase-dependent activity of the MCM complex. Using cryo-EM reconstructions of the CMG complex in different conformations, the authors propose a model where the N-terminal and AAA+ domains of MCM work in concert to translocate along DNA. |
