RESUMO
The rates of acid-catalyzed hydrolysis of a hypermodified nucleoside, wyosine and its 5'-monophosphate were determined at various pH, temperature and buffer concentrations. The results show that despite distinct differences in structure and the glycosyl bond stability, the hydrolysis of wyosine proceeds via cleavage of the C-N bond by A-1 mechanism, analogously to simple nucleosides. Unlike majority of other monophosphates studied so far, wyosine 5'-monophosphate is not more stable than respective nucleoside.
