title: Construction and properties of a ribosome-binding site mutation in gene E of phi X174 bacteriophage.
abstract: Oligodeoxyribonucleotide mutagenesis has been used to produce a G----A mutation at nucleotide 557 of the phi X174 genome. This changes the ribosome-binding sequence GAGG of gene E to GAAG without affecting the amino acid, glutamine, encoded by the overlapping gene D. The phi X174rb(E)557 mutant does not lyse infected Escherichia coli C and therefore results in the accumulation of a large number intracellular mature phage particles. Thus, the mutation inactivates production of the gene E lytic product, presumably by blocking translation of gene E, without affecting other phage functions.
