Chitin synthase activity

WebJan 23, 2024 · Chitin is a highly abundant polymer in nature and an excellent biomaterial with multiple applications. However, the molecular mechanisms of chitin biosynthesis and chitin structural diversity are still unclear. This study explores the molecular mechanisms regulating chitin deposition and dissects the roles of the different factors involved in this … Chitin Synthase is manufactured in the rough endoplasmic reticulum of fungi as the inactive form, zymogen. The zymogen is then packaged into chitosomes in the golgi apparatus. Chitosomes bring the zymogen to the hyphal tip of a mold or yeast cell membrane. Chitin synthase is placed into the interior side of the cell membrane and then activated.
