Abstract
Whether the regulatory protein of an inducible operon for a catabolic pathway is a positive or a negative element in the control of expression is correlated with the frequent or infrequent presence, respectively, of the system's substrate in the natural environment.
摘要
对于分解代谢途径的可诱导操纵子而言，其调节蛋白在表达控制中是正调控元件还是负调控元件，分别与该系统的底物在自然环境中出现的频率高低相关。
