Bombolitins are five naturally occurring heptadecapeptides acting at the membrane level and able to increase the activity of phospholipase A(2). As for other peptides with similar function, the biological activity of bombolitins seems to be mainly due to their ability to form amphipathic helical structures. We synthesized and tested the retro sequence of bombolitin I (retro-bombolitin I). This peptide showed an activity similar to that of the natural sequence and was able to adopt a helical structure in the presence of an amphipathic environment consisting of SDS micelles.

Abstract

Bombolitins are five naturally occurring heptadecapeptides acting at the membrane level and able to increase the activity of phospholipase A(2). As for other peptides with similar function, the biological activity of bombolitins seems to be mainly due to their ability to form amphipathic helical structures. We synthesized and tested the retro sequence of bombolitin I (retro-bombolitin I). This peptide showed an activity similar to that of the natural sequence and was able to adopt a helical structure in the presence of an amphipathic environment consisting of SDS micelles. The secondary structure of this peptide was fully characterized by CD and nmr spectroscopy. (C) 1994 John Wiley and Sons, Inc.
