WebbFeedback inhibition is a normal biochemical process that makes use of noncompetitive inhibitors to control some enzymatic activity. In this process, the final product inhibits the enzyme that catalyzes the first step in a series of reactions. Feedback inhibition is used to regulate the synthesis of many amino acids. http://med.wanfangdata.com.cn/Paper/Detail/PeriodicalPaper_zglcyyzz200102024 out and about fishingWebbto chemical synthesis. In particular, metabolic pathway engineering allows enhanced product titer s by inactivating/blocking the competing pathways, increasing the level of essential intracellular precursors, and overexpressing ratelimiting enzymatic steps. - LBased on the route of - the rohit sharma total runs
