摘要：

Continuous-flow fast-atom bombardment mass spectrometry has been developed to directly monitor cyclic nucleotide (substrate) and its product levels from an on-going phosphodiesterase reaction. Analysis of cAMP and cCMP phosphodiesterase incubates have been performed where the temporal evolution of the enzymic reaction is monitored and the effect of enzyme concentration upon the rate of reaction determined. Quantitative data on the enzyme kinetics have been obtained, in the form of Lineweaver-Burke plots, that are shown to correlate well with well-established radiometric methods.
