pubmed:abstractText |
We have identified the first highly efficient intramolecular general base catalysis (IGBC) of a hydrolysis reaction, in a system where two general bases are available to assist the attack of the same nucleophilic water molecule. The suggested mechanism, available uniquely to a phosphate triester model, is readily available in enzyme active sites, and the results suggest a possible solution to the long-unsolved question of how enzymes are able to activate a water molecule to be a highly effective nucleophile.
