The bacteriophage T4 replisome: a model system for understanding DNA replication mechanisms

The bacteriophage T4 replisome is a complex molecular machine responsible for DNA replication in the T4 phage. It consists of multiple proteins that work together to ensure efficient and accurate replication of the phage genome. The replisome comprises DNA polymerases, helicase, primase, and other accessory proteins, which coordinate leading- and lagging-strand synthesis. Extensive research over the years, including protein analysis, enzyme kinetics, and structural investigations, has provided insights into the organization and function of these proteins, along with their dynamics and coordination at the replication fork. The T4 replisome serves as a useful model system for understanding molecular fidelity, enzymatic interplay, and fundamental principles of DNA replication.
