Conversely, old or damaged catalytic proteins are marked for destruction. The addition of a small protein tag called targets the enzyme for delivery to the proteasome , a barrel-shaped molecular recycling center that shreds the protein back into reusable amino acids. 6. Coenzymes, Cofactors, and Prosthetic Groups
Vmax: The maximum velocity of the reaction when the enzyme is saturated with substrate.Km: The substrate concentration at which the reaction rate is half of Vmax, indicating the enzyme's affinity for its substrate. Conversely, old or damaged catalytic proteins are marked
The catalytic power of an enzyme is rooted in its molecular biology. Most enzymes are globular proteins composed of long chains of amino acids folded into intricate shapes. Conversely, old or damaged catalytic proteins are marked
