Mechanisms of activation of the cryptic cel operon of Escherichia coli K12.

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 activating the operon. The first involves mutations that allow the repressor to recognize the substrates cellobiose, arbutin...
