A new mutation, bglJ4, has been characterized that results in the expression of the silent bgl operon. The bgl operon encodes proteins necessary for the transport and utilization of the aromatic beta-glucosides arbutin and salicin. A variety of mutations activate the operon and result in a Bgl+ phenotype. Activating mutations are located upstream of the bgl(More)
