A Complex of Methylthioadenosine/<i>S</i>-Adenosylhomocysteine Nucleosidase, Transition State Analogue, and Nucleophilic Water Identified by Mass Spectrometry
An enzyme-stabilized nucleophilic water molecule has
been implicated
at the transition state of Escherichia coli methylthioadenosine nucleosidase (<i>Ec</i>MTAN) by transition
state analysis and crystallography. We analyzed the <i>Ec</i>MTAN mass in complex with a femtomolar transition state analogue
to determine whether the inhibitor and nucleophilic water could be
detected in the gas phase. <i>Ec</i>MTAN–inhibitor
and <i>Ec</i>MTAN–inhibitor–nucleophilic water
complexes were identified by high-resolution mass spectrometry under
nondenaturing conditions. The enzyme–inhibitor–water
complex is sufficiently stable to exist in the gas phase
