T2 Bacteriophage vs. T4 Bacteriophage: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 29, 2024
T2 and T4 bacteriophages are both viruses that infect E. coli; T2 has distinct DNA packaging and receptor binding, while T4 is more studied, with unique replication and repair mechanisms.
Key Differences
T2 and T4 bacteriophages are viruses that specifically infect E. coli bacteria. Both belong to the T-even phage group and share a similar structure, with a hexagonal head and a tail. However, T2 bacteriophage has distinct DNA packaging and receptor binding mechanisms compared to T4, which is more extensively studied and understood.
The T2 bacteriophage is known for its unique way of packaging its DNA during the assembly of new virus particles. In contrast, the T4 bacteriophage has been a key model in understanding viral replication and DNA repair mechanisms, making it one of the most studied bacteriophages in molecular biology.
T2 bacteriophage attaches to its host cell using its tail fibers, which recognize specific receptor sites on the E. coli surface. T4 bacteriophage, while also using tail fibers for attachment, has a more complex mechanism of DNA injection into the host, involving the contraction of its tail sheath.
In terms of genetic composition, T2 bacteriophage's genome is slightly less understood compared to T4's. The T4 bacteriophage genome has been extensively sequenced and studied, providing vast insights into viral genetics and molecular interactions with the host.
T2 bacteriophage's research contributions focus more on the fundamental aspects of viral life cycles, whereas T4 bacteriophage has been instrumental in advancing our understanding of gene regulation, protein synthesis, and virus-host interactions.
