BIOMOLECULE: 1 THIS ENTRY CONTAINS THE CRYSTALLOGRAPHIC ASYMMETRIC UNIT WHICH CONSISTS OF 3 CHAIN(S). SEE REMARK 350 FOR INFORMATION ON GENERATING THE BIOLOGICAL MOLECULE(S).NOTE THAT COORDINATES FOR A DIMER FROM A COMPLETE TETRAMERIC MULTIMER REPRESENTING THE KNOWN BIOLOGICALLY SIGNIFICANT OLIGOMERIZATION STATE OF THE MOLECULE CAN BE GENERATED BY APPLYING BIOMT TRANSFORMATIONS GIVEN IN REMARK 350. BOTH NON-CRYSTALLOGRAPHIC AND CRYSTALLOGRAPHIC OPERATIONS ARE GIVEN. | ||||||
| Remark 999 | SEQUENCE The native GLUR-2 is a membrane protein. The protein crystallized by the author is the ...SEQUENCE The native GLUR-2 is a membrane protein. The protein crystallized by the author is the extracellular ligand binding domain of GLUR-2. Transmembrane regions were genetically removed and replaced with a Gly-Thr linker. The sequence, as a result, matches discontinuously with the reference database. |
