Abstract

Solid-state two-dimensional refocused INADEQUATE MAS NMR experiments resolve distinct helical and β-sheet conformational environments for both alanine and glycine in Nephila clavipes dragline silk fibers; the fraction of alanine and glycine in β-sheet structures is determined to be 82% ± 4% and 28% ± 5%, respectively.
