Chitin biosynthesis
WebChitin is one of the most important carbohydrates of the fungal cell wall, and is synthesized by chitin synthases. Chitin can be degraded by chitinases, which are important virulence factors in pathogenic fungi. Knowledge about the biosynthesis and degradation of chitin, and the enzymes responsible, has accumulated in recent years. WebChitin being an important component of fungal cell wall has been a potential drug target. Inhibition of chitin synthase enzymes by structural analogs of the substrate of chitin …
