Web5 Jan 1979 · A protocol is described for the isolation of mutants of the bacteriophage T4 which are specifically defective in the tail fiber assembly or attachment process. The technique utilizes as a selective factor the observation that fiberless particles sediment in a sucrose gradient more rapidly than do fibered particles. Web7 Dec 2024 · The formation of the tail is initiated by the assembly of the adaptor protein gp11 into a dodecameric ring, onto which the hexameric nozzle protein (gp12) assembles ( 11 ). The tail formation is completed by the binding of six gp17 fiber protein trimers, which are responsible for host cell recognition, onto the gp11–gp12 interface ( 12 ).

WebResults: The tail is formed by a tubular structure (proteins gp11 and gp12) surrounded by six fibers. Conclusion: gp11 is a gatekeeper-adaptor protein, and gp12 closes the ejection channel. Significance: Tailed bacteriophages may share a common molecular mechanism to coordinate the switch between DNA packaging and tail assembly. Bacteriophage WebChaperone involved in tail fiber assembly. Remains associated to the tail fiber and participates in the host receptor binding. Binds to the primary receptor (Probable). Two … Web5 Oct 2012 · Phage λ tail contains a hollow tube that consists of 32-stacked disks, where each disk is formed by six subunits of the major tail protein gpV, arranged such that each disk has a central, 3 nm hole. Phage λ uses this channel to eject its DNA, though the tail by itself (without the head) can attach to the host cell. nand cmos回路
