Spectroscopic and structural study of the heterotropic linkage between halide and proton ion binding to GFP proteins: E2(GFP)-br complex

Structure

x-ray diffraction · 1 distinct chain · 12% helix, 51% strand (DSSP).

Ligands and binding sites

• CRO · {2-[(1R,2R)-1-amino-2-hydroxypropyl]-4-(4-hydroxybenzylidene)-5-oxo-4,5-dihydro-1H-imidazol-1-yl}acetic acid · ligand · chains A
• BR · Bromide ion · ion · 4 copies · chains A

Binding sites are the residues within 4.5 Å of a ligand's heavy atoms.

Pockets

2 pockets found on a 1 Å grid, 1 with a druggability of 0.5 or more.

Modifications

Observed in the structure: 2 cofactor (chromophore).
