Abstract

The in vitro neutralization of the killing activity of cloacin DF13 by incubation with its purified receptor protein was shown to be the result of the formation of a direct and specific equimolar complex of both proteins. The binding of cloacin DF13 to its receptor protein did not result in a fragmentation of the cloacin molecules nor in the expulsion of immunity protein from the bacteriocin. The rate of the cloacin DF13-receptor interaction in vitro was found to be enhanced significantly in the presence of peptidoglycan, but lysozyme-treated peptidoglycan did not affect this interaction. Incubation of the cloacin DF13 as well as its receptor protein with peptidoglycan showed that the receptor protein but not the cloacin DF13 was able to bind to the peptidoglycan.
