Effect of a serine-to-aspartate replacement on the recognition of chitin oligosaccharides by truncated hevein. A 3D view by using NMR

The interaction of a synthetically prepared mutant peptide of hevein (a well known chitin-binding lectin) Hev32S19D with chitin oligosaccharides (and chitosan analogues) has allowed us to estimate their affinity constants and associated thermodynamic data. The mutant peptide is able to bind chitin o...
