The SEWING protocol is a method for the rapid generation of denovo backbones that uses large segments of natural protein structure. For definitions of common terms used in SEWING, visit the SEWING Dictionary.
SEWING stands for Structure Extension WIth Native-fragment Graphs. SEWING functions by identifying relatively large sub-structures (typically 2-5 pieces of secondary structure, called segments) from native PDBs, and then assembling these models based on structural similarity.
The workflow below is for an updated version of SEWING not yet released to users. For documentation on the SEWING protocol published by TM Jacobs in a 2016 issue of Science, please refer to the original SEWING workflow.
