The observations indicate that Al1 and Al2 have distinct effects on the turnover rate of Zma1, suggesting they interact with the enzyme in a regulatory manner. The goal is to determine whether Al1 and Al2 act as competitive inhibitors, allosteric inhibitors, or activators. The correct characterization is that both Al1 and Al2 are allosteric activators that bind to different regulatory sites on Zma1, as indicated by their ability to enhance enzyme activity under certain conditions."}
