How are Ring Structures Utilized in Enzyme Catalysis?
Enzymes, which are biological catalysts, frequently contain ring structures in their active sites. These rings, often found in amino acid residues like [histidine]() or [proline](), are crucial for substrate binding and catalysis. For example, the aromatic rings in the active site of [cytochrome P450 enzymes]() facilitate the transfer of electrons necessary for oxidation reactions. The rigidity and specific geometry of these rings also help in proper substrate orientation, enhancing catalytic efficiency.
