Puromycin: Effect On Messenger Rna Synthesis And Beta-Galactosidase Formation In Escherichia Coli 15t


, : Puromycin: Effect On Messenger Rna Synthesis And Beta-Galactosidase Formation In Escherichia Coli 15t. Science 148(3668): 371-373

Incubation of Escherichia coli 15T(-) in the presence of puromycin inhibits the inducible formation of beta-galactosidase to a greater extent than it inhibits protein synthesis. In E. coli 33.00 beta-galactosidase formation is also more sensitive to the presence of puromycin than is protein synthesis. In the presence of glycerol (but not in its absence) puromycin prevents the production of messenger RNA for beta-galactosidase, presumably as a result of catabolite repression.
