In vitro assembly of bacteriophage Lambda heads.
The assembly of plaque-forming particles in cell-free extracts of induced lambda lysogens was observed two ways. (i) DNA isolated from a lambda-related phage, 434 for example, is added to an extract of an induced lambda lysogen, and plaque-formers with the genotype of the added DNA are detected. (ii) One extract from an induced lambda lysogen that carries an amber mutation in one of the head ge...
متن کاملMutant of Lambda Bacteriophage Producing a Thermolabile Endolysin.
Campbell, Allan (University of Rochester, Rochester, N.Y.) and Alice del Campillo-Campbell. Mutant of lambda bacteriophage producing a thermolabile endolysin. J. Bacteriol. 85:1202-1207. 1963.-Endolysin from lambda bacteriophage and a temperature-sensitive mutant thereof was partially purified. The mutant enzyme was distinguishable from the wild type by its greater rate of inactivation by high ...
متن کاملIn vivo gene delivery and expression by bacteriophage lambda vectors
AIMS Bacteriophage vectors have potential as gene transfer and vaccine delivery vectors because of their low cost, safety and physical stability. However, little is known concerning phage-mediated gene transfer in mammalian hosts. We therefore performed experiments to examine phage-mediated gene transfer in vivo. METHODS AND RESULTS Mice were inoculated with recombinant lambda phage containin...
متن کاملExpression of the argA gene carried by a defective lambda bacteriophage of Escherichia coli.
Evidence is presented that the increase in specific activity of N-acetylglutamate synthase observed upon heat induction of Escherichia coli (lambdadargA) is primarily due to a gene dosage effect.
متن کاملControl of transcription of the repressor gene in bacteriophage lambda.
The rate of transcription of the structural gene for repressor (cI gene) in bacteriophage lambda is controlled by the amount of active repressor in the cell. When the (reversibly) thermolabile repressor in a bacterium lysogenic for lambdacI(857) is inactivated by heat, the rate of repressor gene transcription immediately falls. If the repressor is renatured, synthesis of repressor messenger is ...
