In this article we will discuss about the life cycle of phage M13. M13 uses the F pilus of E. coli to infect the cell. Protein pill located on the tip of M13 contacts the TolA protein located on the pilus of host cell. This interaction causes a conformational change in pVIlI from 100% alpha-helix […]
