โฆ Synopsis
Aminoglycoside antibiotics inhibit protein biosynthesis and various ribozymes. Structural electrostatic complementarity can explain the inhibition mechanism of the hammerhead ribozyme: positively charged ammonium groups match the negatively charged metalion-binding pockets created by the RNA fold's electrostatic field.

## Background: Divalent metal ions serve as structural as well as catalytic cofactors in the hammerhead ribozyme reaction. the natural cofactor in these reactions is mg(ii), but its spectroscopic silence makes it difficult to study. we previously showed that a single tb(iii) ion inhibits the hammer
