RIBONUCLEASE T1 COMPLEXED WITH 2',3'-CGPS, 1 DAY
|
OverviewOverview
Here we present a time-resolved crystallographic analysis of the, hydrolysis of exo (Sp) guanosine 2',3'-cyclophosphorothioate by RNase T1., The use of a slow substrate and fast crystallization methods made it, possible to perform the study with conventional data-collection, techniques. The results support the idea that the hydrolysis reaction, proceeds through a mechanism that is the inverse of the, transesterification reaction. In addition, the structures provide an, explanation for the differential behavior of RNase T1 towards exo- and, endo-cyclic thiophosphates.
