The LLP domains. (A) Helical wheel diagrams showing the amphipathic nature of each LLP domain. The coloring scheme is from Benner et al. and graphs were generated using a java applet available at the PredictProtein server . (B) Primary amino acid sequence of LLP peptides which correspond to the LLP-1, -2, and -3 domains of the TM protein are given from the helical wheels in (A).
