| Popis: | Bacteriocin susceptibilities indicate that during cloacin DF13 uptake the F porin of Enterobacter cloacae plays a similar role to that reported for the OmpF porin of Escherichia coli during colicin A entry. The translocatory activities of these two porins during the bacteriocin uptake can be substituted by the porins D and OmpC, respectively, under conditions not requiring the receptor binding step. Using anti-peptide antibodies, a peptide located in the internal loop L3 of the Escherichia coli OmpF porin was identified in the D and F porins of Enterobacter cloacae. The results demonstrated the existence of a close relationship between porins in terms of both antigenic determinants and bacteriocin susceptibilities. |
