From: Analysis of electric moments of RNA-binding proteins: implications for mechanism and prediction
Distribution of positively charged (Lys and Arg) residues (blue surface filled) and negatively charged (Asp and Glu) residues (red surface filled) in HI1333, a hypothetical protein from Haemophilus influenzae (PDB ID 1JO0) from the protein data bank. Protein has a significantly high dipole moment and its RNA-binding region seems to be clearly separated from the negatively charged region by a vertical plane.
