Workflow of the Protein NCS-based Structure Extender (PNS Extender). Intermediate partial models are examined for symmetric dependencies between stretches of two fragments (a). An initial match is found between green and blue regions (b, red blocks). The initial match is extended in both directions of the chain fragments (c, orange blocks). Once the extension is finished and the r.m.s.d. between the extended matches (red blocks in d) is still below the acceptance threshold, each extension (e, overlayed blocks) is NCS-transformed, as shown by arrows, onto the other fragment. Finally, longer extended green and blue fragments are obtained (f) and their extended parts (f, yellow blocks) are input as guides for protein-chain tracing.
