THE REMARK 3 DIFFERENCE DENSITIES ALSO AFFECT THE ATOMIC-POSITION REMARK 3 REFINEMENT OF VAL 68. THE DIFFERENCE FEATURES MIGHT BE REMARK 3 EXPLAINED AS A SUBSET (<30%) OF MOLECULES THAT HAS FAILED REMARK 3 TO UNDERGO THE COMPLETE FORMATION OF THE FLUOROPHORE. THE REMARK 3 LOOP RESIDUES 157 AND 158 ARE DISORDERED. A NUMBER OF REMARK 3 SURFACE RESIDUES HAVE TRUNCATED SIDE CHAINS DUE TO WEAK REMARK 3 OR NO DENSITY.
