👉 Pseudotributary is a type of enzyme that catalyzes the reversible bond formation between two amino acids. It can also be defined as an enzyme that has an allosteric effect, meaning it changes its activity depending on the concentration of another enzyme or substrate present in the reaction mixture. In other words, pseudotributary enzymes are enzymes whose activity is affected by changes in their substrate concentration but not by changes in their activation energy. This means that a change in the substrate
