Sequence of the fruB gene of Escherichia coli encoding the diphosphoryl transfer protein (DTP) of the phosphoenolpyruvate: sugar phosphotransferase system

Abstract

The Escherichia coli genome sequencing project in the 47 to 48 centisome region has resulted in the sequencing of the complete fructose operon (fruBKA). Due to a single base insertion, the presence of the fruB gene went unnoticed. the revised nucleotide sequence of the fruB gene, the deduced amino acid sequence of its protein product, the diphosphoryl transfer protein of the phosphoenolpyruvate: sugar phosphotransferase system, and putative transcriptional regulatory signals of the fru operon of E. coli are here presented and compared with that from Salmonella typhimurium. © 1994.
