Genetics - 1 Mar 1990
Parker L L, Hall B G
Abstract excerpt
The cel (cellobiose utilization) operon of Escherichia coli K12 is not expressed in the wild-type organism. However, mutants that can express the operon and thereby utilize the beta-glucoside sugars cellobiose, arbutin and salicin are easily isolated. Two kinds of mutations are capable of activat...
