WebThe tail of the bacteriophage includes the tail sheath, base plate and tail fibers, which are made of different proteins. The long tail fibers are used by the bacteriophage to attach itself to the bacterium and the virus then inserts its genetic material inside of the host cell to begin the replication process. The bacteriophage uses the host ... WebTail sheath proteins (TShP) have a particular role in the structural biology of phages as a molecular engine for viral infection. The first object in the study of sheath proteins was gp18 from the classic phage T4. Unfortunately, it was not the best choice, because the recombinant protein tended to polymerise, forming polysheaths. Web17 Dec 2014 · ABSTRACT Bacteriophage T4 is the most well-studied member of Myoviridae, the most complex family of tailed phages. T4 assembly is divided into three independent pathways: the head, the tail and the long tail fibers. The prolate head encapsidates a 172 kbp concatemeric dsDNA genome.
