Molecule: Egfp-Scnn1g Chimera
Chain: C
Engineered: Yes
Other_details: The Protein Is Egfp-Scnn1g Chimera. Transmem Helices Have Been Built With Poly Unk Since The Density For Transmembrane Domain Is Not Good Enough To Accurately Build Residues That Have Not Been Built Is Due To Flexible Areas Protein Where Density Is Missing. The First 260 Residues Is Tag And A Strep-Tag Followed By Egfp (Uniprot Accession Cod C5mky7). The Full Sequence Is Described In Sequence Details
