Abstract

Using circular dichroism, this study investigated the secondary structure of the influenza A M2 transmembrane domain. When reconstituted into 1,2-dioleoyl-sn-glycero-3-phosphocholine liposomes, the M2 transmembrane domain was found to adopt a predominantly α-helical secondary structure which was unaffected by both temperature and the addition of 1-aminoadamantane hydrochloride. Reconstitution into 1,2-dioleoyl-sn-glycero-3-phosphoglycerol liposomes resulted in a marked decrease in helical content.
