The Escherichia coli O157:H7 EDL933 genome is 5.62 Million bp long and contains approximately 5554
predicted genes. |
The sequence was released 02/24/2001 by the University of Wisconsin-Madison, USA, and was described
in Nucleic Acids Res 26:4196-204 (1998) Burland V, Shao Y, Perna NT, Plunkett G, Sofia HJ, et al. "The complete DNA sequence and analysis of the large virulence plasmid of Escherichia coli O157:H7.
Abstract: The complete DNA sequence of pO157, the large virulence plasmid of EHEC strain O157:H7 EDL 933, is presented. The 92 kb F-like plasmid is composed of segments of putative virulence genes in a framework of replication and maintenance regions, with seven insertion sequence elements, located mostly at the boundaries of the virulence segments. One hundred open reading frames (ORFs) were identified, of which 19 were previously sequenced potential virulence genes. Forty-two ORFs were sufficiently similar to known proteins for suggested functions to be assigned, and 22 had no convincing similarity with any known proteins. Of the newly identified genes, an unusually large ORF of 3169 amino acids has a putative cytotoxin active site shared with the large clostridial toxin (LCT) family and proteins ...
