DetailsThe SPOR domain consists of residues 344-428. Structure analysis and statistics in the accompanying publication consider only this portion of the construct. Residues 323-338 are poorly constrained and represent a His-tag plus linker; this region accounts for roughly half of the close contacts and Ramachandran outliers noted in this file.
