[http://xray.bmc.uu.se/hicup/ HIC-Up] reports the occurrence of Sec in [http://xray.bmc.uu.se/hicup/CSE/ 11 entries] in the [[PDB]]. The highest [[Resolution|resolution]] entry is [[1kqf]] (1.6 &Aring;), with Sec at 196 in chain A. To see it, go to [[1kqf]] and click on CSE under Non-Standard Residues.
In January, 2022, '''76 entries''' in the [[wwPDB]] contain Sec. An example of naturally-occuring Sec is human glutathione peroxidase 4, where Sec46 occurs in the catalytic site. [[6hn3]] is the wild type, while [[6hkq]] has an inhibitor covalently bound to the Sec.
