Escherichia Coli
Reports outline Escherichia coli study results from Food & Drug Administration
May 27th, 2008
According to a study from the United States, "In silico analyses of previously sequenced strains of Escherichia coli 0157:117, EDL933 and Sakai, localized the gene cluster for the utilization of N-acetyl-D-galactosamine (Aga) and D-galactosamine (Gam). This gene cluster encodes the Aga phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS) and other catabolic enzymes responsible for transport and catabolism of Aga." "As the complete coding sequences for enzyme IIA (EIIA)(Aga/Gam), EIIBAga, EIICAga, and EIIDAga of the Aga PTS are present, E. coli 0157:H7 strains normally are able to utilize Aga as a sole carbon source. The Gam PTS complex, in contrast, lacks...
