N-ribohydrolases and transferases act on nucleosides, nucleotides and oligonucleotides to effect base removal. Advances in mechanistic and structural analysis have established that enzymes of N-riboside scission act by combinations of leaving-group and ribosyl activation. Alternative O-riboside substrates have been developed for mechanistic diagnosis. Transition-state structures have been determined, and powerful inhibitors have been designed from structural and transition-state information.
