摘要：

A hybrid QM/MM computational study of acid-catalysed hydrolysis of a model for adenosine monophosphate solvated by ca. 500 water molecules suggests the possibility of both stepwise D-N*A(N) and concerted A(N)D(N) mechanisms, but agreement between calculated and experimental kinetic isotope effects for multiple substitutions indicate the former mechanism.
