Caption: Molecular computer graphics image of a uridine- vanadate complex, a substrate of ribonuclease-A, an enzyme involved in the destruction of messenger RNA (mRNA) in the cytoplasm of bacteria. Enzymes are biological catalysts, proteins that speed up the rates of reactions within cells. Each enzyme is specific for a particular reaction; interaction occurs between an active site on the enzyme & a reactant (or substrate) due to the arrangement of mutually attractive groups of atoms. Weak bonds are typically formed between enzyme & substrate. Here, the substrate's atomic backbone appears in stick form, surrounded by its Van der Waals bonding surface (orange & blue spheres).
