Integral membrane protein P16 of bacteriophage PRD1 stabilizes the adsorption vertex structure.
The icosahedral membrane-containing double-stranded DNA bacteriophage PRD1 has a labile receptor binding spike complex at the vertices. This complex, which is analogous to that of adenovirus, is formed of the penton protein P31, the spike protein P5, and the receptor binding protein P2. Upon infection, the internal phage membrane transforms into a tubular structure that protrudes through a vert...
متن کاملEfficient DNA packaging of bacteriophage PRD1 requires the unique vertex protein P6.
The assembly of bacteriophage PRD1 proceeds via formation of empty procapsids containing an internal lipid membrane, into which the linear double-stranded DNA genome is subsequently packaged. The packaging ATPase P9 and other putative packaging proteins have been shown to be located at a unique vertex of the PRD1 capsid. Here, we describe the isolation and characterization of a suppressor-sensi...
متن کاملTale of two spikes in bacteriophage PRD1.
Structural comparisons between bacteriophage PRD1 and adenovirus have revealed an evolutionary relationship that has contributed significantly to current ideas on virus phylogeny. However, the structural organization of the receptor-binding spike complex and how the different symmetry mismatches are mediated between the spike-complex proteins are not clear. We determined the architecture of the...
متن کاملIdentification and mutational analysis of bacteriophage PRD1 holin protein P35.
Holin proteins are phage-induced integral membrane proteins which regulate the access of lytic enzymes to host cell peptidoglycan at the time of release of progeny viruses by host cell lysis. We describe the identification of the membrane-containing phage PRD1 holin gene (gene XXXV). The PRD1 holin protein (P35, 12.8 kDa) acts similarly to its functional counterpart from phage lambda (gene S), ...
متن کاملGlobal changes in cellular gene expression during bacteriophage PRD1 infection.
Virus-induced changes in cellular gene expression and host physiology have been studied extensively. Still, there are only a few analyses covering the entire viral replication cycle and whole-host gene pool expression at the resolution of a single gene. Here we report changes in Escherichia coli gene expression during bacteriophage PRD1 infection using microarray technology. Relative mRNA level...
