Dictionary of amino acid change properties. Keys are descriptions of the change (e.g., “charge gain, positive”), and values are dictionaries with properties: - property: The property being changed (e.g., “charge”, “volume”). - from: The original value of the property before the change. - to: The new value of the property after the change. This dictionary can be used to look up the nature of changes in amino acid properties.
