Abstract

The conformation of the non-glycosylated recombinant form of the extracellar domain of rat MOG (rMOG(1-125)) dissolved in different solvent conditions was studied by CD spectroscopy. The results show that rMOG(1-125) exhibits a predominantly β sheet conformation in aqueous buffer solution at pH 7.5 and that this β-form is stabilized by zwitterionic phospholipids, DPC and LPCP. The a helical content of the protein can increase from 9% to up to 20% when TFE or anionic detergent LPAP and SDS are added.
