Question

What are receptor sites in bacteriophages?

Answer 1

Receptor sites in bacteriophages:

1. Bacteriophages do not link to the surface of the host cell at random; instead, they bind to specific receptor sites on the cell's surface.
2. Depending on the phage, the nature of these receptors differs.
3. Cell wall proteins and lipopolysaccharides, flagella, teichoic acids, and pilli are all receptors.
4. E.coli T-even phages use cell wall proteins or lipopolysaccharides as receptors.
5. Differences in receptor properties explain some of the phage-host preferences.
