title: Characterization and sequence of a 33-kDa enterohemolysin (Ehly 1)-associated protein in Escherichia coli.
abstract: The nucleotide sequence of the 2.1-kb EcoRI-AccI fragment of the enterohemolysin (Ehly)-associated plasmid, pEO21, has been determined. A third of this sequence encodes a 29.6-kDa protein, and coincides with the location of Tn1725 insertions which inactivate the production of Ehly. A protein of similar size (33-35 kDa) was found to be produced in large amounts by JM83[pEO21] and found to be immunologically related to the approximately 65-kDa protein made by the parental strain, C3888. DNA sequences coding for the 29.6-kDa protein of phi C3888, now designated Ehly 1, were found only in some enterohemolytic Escherichia coli indicating the existence of multiple, genetically different Ehlys.
