The phosphoenolpyruvate (PEP): carbohydrate phosphotransferase system (PTS) is found
only in bacteria, where it catalyzes the transport and phosphorylation of numerous
monosaccharides, disaccharides, amino sugars, polyols, and other sugar derivatives. To
carry out its catalytic function in sugar transport and phosphorylation, the PTS uses PEP as
an energy source and phosphoryl donor. The phosphoryl group of PEP is usually transferred
via four distinct proteins (domains) to the transported sugar bound to the respective …

Volume 70, no. 4, p. 939–1031, 2006. Page 941, column 2, lines 5–9: It is incorrect that
growth of Escherichia coli on fructose and a less favorable carbon source leads to diauxic
growth. In fact, J. Monod (Recherches sur la Croissance des Cultures Bactériennes, 1942)
reports that he observed biphasic growth of E. coli cells with glucose or mannitol as the
“preferred” carbon source but not with fructose. Page 954, column 2: The first paragraph of
the “Diauxic Growth” section refers specifically to the diauxic growth of Bacillus subtilis, the …
