Characterization and nucleotide sequence of the cryptic cel operon of Escherichia coli K12.

Genetics - 1 Mar 1990

Parker L L, Hall B G

Abstract excerpt

Wild-type Escherichia coli are not able to utilize beta-glucoside sugars because the genes for utilization of these sugars are cryptic. Spontaneous mutations in the cel operon allow its expression and enable the organism to ferment cellobiose, arbutin and salicin. In this report we describe the structure and nucleotide sequence of the cel operon. The cel operon consists of five genes: celA, whose function is...
