Caption: Molecular computer graphics image of a close-up of the interaction of ribonuclease-A with its substrate. Ribonuclease-A is an enzyme involved in the destruction of messenger RNA (mRNA) in the cytoplasm of bacteria. Here, the substrate (left, orange & blue dots & sticks) fits into a depression (the active site) in the surface of the enzyme (yellow). Enzymes are biological catalysts, proteins that speed up the rates of reactions within cells. Each enzyme is specific for a particular reaction; interaction occurs (typically as a weak bond) between enzyme & substrate at the active site, due to the arrang- ement of mutually-attractive groups of atoms
