Identification of uhp polypeptides and evidence for their role in exogenous induction of the sugar phosphate transport system of Escherichia coli K-12.

Cells of Escherichia coli possess a transport system that catalyzes the accumulation, in unaltered form, of a variety of sugar phosphates. Induction of the transport activity occurs in response to external glucose 6-phosphate and does not require detectable entry of this inducer. To define the genes that encode the Uhp transport system and those that… CONTINUE READING
