Capsomer proteins of bacteriophage PRD1, a bacterial virus with a membrane

Virology. 1990 Aug;177(2):445-51. doi: 10.1016/0042-6822(90)90508-o.


Bacteriophage PRD1 infecting Escherichia coli and Salmonella typhimurium translocates its membrane from the host plasma membrane to the virus particle. One obligatory component in this process is the major capsid protein. In this investigation we describe characteristics of the homomultimeric major and minor capsid proteins including the sequences of the corresponding genes. The minor capsid protein was found to contain a short collagen-like region (Gly-X-Y)6. This is the first time this motif has been reported for a prokaryotic protein.
