Induction and displacement of an helix in the 6725 SERA peptide analogue confers protection against P. falciparum malaria.

"The protein called serine repeat antigen (SERA) is a Plasmodium falciparum malaria antigen; high activity erythrocyte binding peptides have been identified in this protein. One of these, the 6725 peptide (non-immunogenic and non-protective), was analyzed for immunogenicity and protective activ...
