Control of transcription of gal repressor and isorepressor genes in Escherichia coli.

abstract：:Most bacteriophages (phages) release their progeny through the action of holins that form lesions in the cytoplasmic membrane and lysins that degrade the bacterial peptidoglycan. Although the function of each protein is well established in phages infecting Streptococcus pneumoniae, the role--if any--of the powerful ba...
