title: Control of gene function in bacteriophage Tr. 3. Preventing the shutoff of early enzyme synthesis.
abstract: Synthesis of early T4 protein, which is normally shut off at 10 min after infection, continues until lysis when host cells have been preinfected with T3 sam(+). In host cells preinfected with T3 sam(-), synthesis of early enzymes is shut off as normal. Thus, S-adenosylmethionine is required for the turnoff of early T4 functions (at least when host cells have been preinfected with T3).
