    • Structure

    • Alpha helix (1 helices; 26 residues)
    • Structure Description

    • In DPC micelles, PlnF has a long central alpha-helix (residues 7-32) with a kink of 38+/-7 degrees at Pro20. There is some flexibility in the helix in the kink region. The helix in plnF is polar in its N-terminal half and amphiphilic in its C-terminal half. plnF has one such motif at residues 30 to 34. The helix in plnF is polar in its N-terminal half and amphiphilic in its C-terminal half. PlnF has one GxxxG motif at residues 30 to 34.

    • A strain-specific antagonistic activity was detected at nanomolar concentrations when PlnE and PlnF were combined. Complementary peptides were at least 103 times more active when they were combined than when they were present individually, and optimal activity was obtained when the complementary peptides were present in approximately equal amounts.
