A common allosteric mechanism regulates homeostatic inactivation of auxin and gibberellin
Enzymatic inactivation of gibberellins and auxin, via GA2ox3 and DAO respectively, contributes to hormone homeostasis in plants. Here Takehara et al. show that both enzymes multimerize in a substrate-concentration-dependent manner, and that this multimerization leads to increased enzyme activity.
