ORC-Mediated DNA Bending: Key to Replication Licensing in Budding Yeast

Quick Summary

• The Proceedings of the National Academy of Sciences, Volume 122, Issue 14 (April 2025), highlights the critical role of the origin recognition complex (ORC) in DNA replication.
• ORC functions as a replication initiator, engaging with origin DNA through an intricate site selection process.
• It is instrumental in recruiting two minichromosome maintenance (MCM) hexameric rings arranged in a head-to-head orientation to facilitate DNA replication.
