Characterization of the gcd gene from Escherichia coli K-12 W3110 and regulation of its expression.


ABSTRACT: DNA sequence and expressional analyses of the gcd gene of Escherichia coli K-12 W3110 revealed that two promoters that were detected were regulated negatively by cyclic AMP and positively by oxygen. Sequence conservation of the gcd gene between E. coli K-12 W3110 and PPA42 suggests that glucose dehydrogenase is required for the E. coli cells, even though it ordinarily exists as an apoprotein.
