The calculated results indicate that there are two absolutely opposite regions in the vicinity of 5-FU. In one of the regions, water molecules can assist the tautomerism from 5-FU to its enol form 5-FU(superscript *, whereas in another region, water molecules can protect 5-FU from tautomerizing to 5-FU(superscript *).
