Representation of molecular electrostatic potentials of biopolymer by self‐organizing feature map

The Kohonen self‐organizing map was introduced to map the protein molecular surface features. The protein or polypeptide properties, such as shape and molecular electrostatic potential, can be visualized by self‐organizing map, which was trained by the 3D surface coordinates. Such maps allow the visual comparison of molecular properties between proteins having common topological or chemical features.
