Barrel Shape and Chromophore Rigidity Predict Fluorescent-Protein Photophysics
Cross-sectional barrel geometry across 908 FP crystal structures in the RCSB PDB is analyzed by principal component analysis (PCA)-based axis determination and convex hull analysis of protein-atom slices at the chromophore plane; 780 structures (210–245 residues, with the chromophore-containing chain selected in FP-com...
