Posttranscriptional modulation of bacteriophage P22 scaffolding protein gene expression.
The bacteriophage P22 late operon contains 2 genes whose products are required for cell lysis and 13 genes whose products are involved in the morphogenesis of the phage particle. This operon is under the positive control of the phage gene 23 product and is thought to have a single promoter. The expression of one of these late genes, the scaffolding protein gene, is autogenously modulated indepe...
متن کاملStructure and functions of the bacteriophage P22 tail protein.
The product of gene 9 (gp9) of Salmonella typhimurium bacteriophage P22 is a multifunctional structural protein. This protein is both a specific glycosidase which imparts the adsorption characteristics of the phage for its host and a protein which participates in a specific assembly reaction during phage morphogenesis. We have begun a detailed biochemical and genetic analysis of this gene produ...
متن کاملThree-dimensional structure of the bacteriophage P22 tail machine.
The tail of the bacteriophage P22 is composed of multiple protein components and integrates various biological functions that are crucial to the assembly and infection of the phage. The three-dimensional structure of the P22 tail machine determined by electron cryo-microscopy and image reconstruction reveals how the five types of polypeptides present as 51 subunits are organized into this molec...
متن کاملGenetics of bacteriophage P22. II. Gene order and gene function.
Although large numbers of temperate phages are known to exist in nature, only a small number of these have been examined in much detail. Foremost among these is the coliphage ~, which has been studied in great depth over the past two decades. However, it is already quite clear that phage ~ represents only one alternative among many with respect to any of its interesting properties. Most other t...
متن کاملPurification and characterization of bacteriophage P22 Xis protein.
The temperate bacteriophages lambda and P22 share similarities in their site-specific recombination reactions. Both require phage-encoded integrase (Int) proteins for integrative recombination and excisionase (Xis) proteins for excision. These proteins bind to core-type, arm-type, and Xis binding sites to facilitate the reaction. lambda and P22 Xis proteins are both small proteins (lambda Xis, ...
