    • Structure

    • Alpha helix (3 helices; 19 residues)

    • Structure Description

    • In DPC micelles, PlnE has an N-terminal alpha-helix (residues 10-21), and a C-terminal alpha-helix-like structure (residues 25-31). Both helices in plnE are amphiphilic, while the helix in plnF is polar in its N-terminal half and amphiphilic in its C-terminal half. PlnE has two GxxxG motifs which are putative helix-helix interaction motifs, one at residues 5 to 9 and one at residues 20 to 24.
