Separation of peripheral polypeptides from soybean lipid extracts and their effects on structural organization of phospholipids
- 26 Downloads
Fluorescence assay of soybean lipid extract showed the presence of polypeptides with tryptophan residues in hydrophobic and polar microenvironment. The peripheral polypeptide with polar tryptophan can be separated from phospholipids in solution with high ionic strength.31P nuclear magnetic resonance spectroscopy demonstrated that this polypeptide stabilized the phospholipid bilayer.
