Primary adsorption site of phage PBS1: the flagellum of Bacillus subtilis
Journal of Virology
|March 1, 1968
Abstract:
The adsorption of Bacillus subtilis phage PBS1 was studied, and it was demonstrated that the primary adsorption site for this phage is the flagellum of B. subtilis. The capacity of flagella to function for motility may be lost without the loss of their capacity to adsorb the phage and permit infection. Deoxyribonucleic acid injection by the phage is inhibited by cyanide, suggesting the requirement for cellular energy in the infection process.
Insights
Bacillus subtilis phage PBS1 primarily adsorbs to the flagellum of B. subtilis. Cellular energy is required for deoxyribonucleic acid injection during phage infection.
Area of Science:
- Microbiology
- Molecular Biology
- Bacteriology
Background:
- Bacillus subtilis is a common soil bacterium.
- Bacteriophages are viruses that infect bacteria.
- Phage-host interactions are crucial in microbial ecology and biotechnology.
Purpose of the Study:
- To investigate the adsorption mechanism of Bacillus subtilis phage PBS1.
- To identify the primary adsorption site of phage PBS1 on B. subtilis.
- To understand the energy requirements for phage PBS1 infection.
Main Methods:
- Studying phage adsorption to bacterial cells.
- Analyzing the role of flagella in phage binding.
- Investigating the effect of metabolic inhibitors (cyanide) on phage infection.
Main Results:
- The flagellum of B. subtilis was identified as the primary adsorption site for phage PBS1.
- Flagella can retain adsorption capacity for phage PBS1 even if motility is impaired.
- Cyanide inhibition of deoxyribonucleic acid injection indicates an energy-dependent infection process.
Conclusions:
- Phage PBS1 utilizes bacterial flagella for initial attachment.
- Bacterial flagella play a dual role in motility and phage susceptibility.
- Phage infection by PBS1 requires host cell energy for DNA translocation.
