WebbThereafter, for sorted segments that are not predicted as transmembrane, server runs PSIPRED to calculate their propensity to be helical, in b-sheets or in random coil in the context of the protein. Segments are also examined to see if their physicochemical properties correspond to those of known lipid-binding amphipathic helices. Webb11 juni 2008 · Prediction of transmembrane helices (TMH) in α helical membrane proteins provides valuable information about the protein topology when the high resolution structures are not available.
