Archaeal organisms possess Cdc45 and GINS homologs that are likely to serve similar functional roles, but their structural interactions with the MCM helicase and hence their mechanism of MCM activation are not as well understood as for their eukaryotic counterparts. We present the crystal structure of the S. solfataricus GINS tetrameric complex and illustrate that a subdomain would need to move to accommodate known archaeal GINS-complex interactions and to generate an S. solfataricus CMG complex analogous to that of eukaryotes.

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.
The crystal structure of proliferating cell nuclear antigen 1 from the thermophilic archaeon A. pernix was determined at 2.00 Å resolution. This crystal structure revealed unique features in the N-terminus, including a PIP-box-like sequence, suggesting potential interactions with other proliferating cell nuclear antigens.
