Recognition and catalysis in nucleic acid chemistry.
The enzyme ribonuclease A catalyzes the cleavage of RNA, using the imidazole groups of histidine-12 and histidine-119 as its principal catalytic groups. Model studies show that RNA can be cleaved by imidazole buffer itself and that, as in the enzyme, a bell-shaped pH vs. rate profile is seen. This i...
