266 Otvos Fig. 3. Schematic presentation of the design of the second-generation (4)M2e-S1-S2 construct. The numbers indicate the number of amino acid residues in each peptide side chain. during the necessary dimerization reaction. Since an increasing amount of evidence suggests that the immunogenic part of the M2e fragment is embedded at the N-terminal half, the second-generation vaccine candidate is further simplified by eliminating eight C-terminal M2e residues. The linear lysinebased construct appears to be suitable for mimicking the M2 four-helix bundle. An analogous four-helix bundle of the bee venom melittin was successfully assembled on a similar scaffold, where alanines were placed in between melittin side chains 1 and 2 as well as 3 and 4, and a turn-forming Gly-Pro dipeptide between the melittin-carrier lysines 2 and 3 (17). In this chapter the synthetic strategy for the construction of the second-generation (4)M2e-S1-S2 construct is detailed. 2. Materials 2.1. Equipment 1. PS3 automated peptide synthesizer (Protein Technologies) (see Note 1). 2.
