Fig. 3: The X-ray diffraction pattern of recombinant silk protein fibers.
From: Structural conversion of the spidroin C-terminal domain during assembly of spider silk fibers
Individual diffraction patterns (a, b) and azimuthally averaged pattern (c, d) of fibers from the CT domain (a, c) and the whole 4RepCT construct (b, d). The size of the side chains determines the packing of crystalline regions and thereby the inter-sheet distances.
