Identification of the Catalytic Mg(2+) Ion in the HDV Ribozyme

The hepatitis delta virus ribozyme catalyzes an RNA cleavage reaction using a catalytic nucleobase and a divalent metal ion. The catalytic base, C75, serves as a general acid and has a pK(a) shifted towards neutrality. Less is known about the role of metal ions in the mechanism. A recent crystal str...
