Abstract:
We performed an in-depth computational image analysis of the baseplate-tail complex of the M4 vibriophage and identified seven major densities in its baseplate, which notably share structural similarities with baseplate modules of a number of other bacteriophages belonging to different species. Employing computational analysis, we explained the helical organization of the sheath protein, wrapping the tail tube. Based on the results obtained in this work along with the proteomics information published previously, we are able to decipher the plausible roles assigned to the different components of the M4 baseplate during infection of the host.
