Using short portions (7-11 amino acid) rich in positively charged residues from either human lactoferricin or the MARCKS protein as templates, a panel of 70 peptides each possessing a specific chemical structure was synthesized. Subsequent functionalization of such azide groups via Staudinger or "Click" chemistry should provide a convenient method for linking proteins with a diverse array of probes, biomolecules, surfaces and other materials under mild conditions. Moreover, the advantages of peptide and protein chemical synthesis over recombinant-DNA methods are increasingly being used to provide rapid structure-activity information of complex bioactive peptides, small proteins and functional receptor domains. Thus, these new peptides bear all of the requirements which are necessary for formation of cooperatively interacting helical structures and, furthermore, contain domains for cooperative sheet aggregation as well. ./cache/cord-022779-himray6q.txt ./txt/cord-022779-himray6q.txt
