Abstract

A galactose-, 1, and a cellobiose derivative, 2, have been site selectively, post- translationally, incorporated into a folded helix-loop-helix dimer LA-42b in a one step reaction at room temperature. The structural effects on the folded peptide upon glycosylation have been studied by CD and NMR spectroscopy. The negative value of the mean residue ellipticity of the folded peptide, LA-42b, was raised from− 19000±1000 to− 21200±1000 ...
