Nucleotide sequence of the ugp genes of Escherichia coli K-12: homology to the maltose system.

The nucleotide sequence of the ugp genes of Escherichia coli K-12, which encode a phosphate-limitation inducible uptake system for sn-glycerol-3-phosphate and glycerophosphoryl diesters, was determined. The genetic organization of the operon differed from previously published results. A single promoter, containing a putative pho box, was detected by S1… CONTINUE READING
