Escherichia coli Cells with Increased Levels of DnaA and Deficient in Recombinational Repair Have Decreased Viability

Grigorian, Aline V., Lustig, Rachel B., Guzmán, Elena C., Mahaffy, Joseph M., Zyskind, Judith W.

The dnaA operon of Escherichia coli contains the genes dnaA, dnaN, and recF encoding DnaA, β clamp of DNA polymerase III holoenzyme, and RecF. When the DnaA concentration is raised, an increase in...

Regulation of Staphylococcal Penicillinase Synthesis

Imsande, John, Zyskind, Judith W., Mile, Imre

5-Methyl tryptophan was found to be an efficient inducer of penicillinase synthesis in Staphylococcus aureus. Addition of actinomycin D or tryptophan to the culture medium shuts off the 5-methyl...

Specificity of a Bacteriolytic Enzyme from Pseudomonas aeruginosa1

Lache, Marvin, Hearn, Walter R., Zyskind, Judith W., Tipper, Donald J., Strominger, Jack L.

A bacteriolytic enzyme isolated from shake-flask cultures of Pseudomonas aeruginosa and capable of lysing cells of Staphylococcus aureus was purified approximately 500-fold by passage through...

The Synchrony Phenotype Persists after Elimination of Multiple GATC Sites from the dnaA Promoter of Escherichia coli

Wilkinson, Terry G., Kedar, G. C., Lee, Chi, Guzmán, Elena C., Smith, Douglas W., Zyskind, Judith W.

To examine whether methylation of the GATC sites present in the dnaA promoter region is responsible for the strict temporal coordination of initiation events at oriC as measured by the synchrony of...
