A. fumigatus α-(1,3) Glucan Production Service
What Is A. fumigatus α-(1,3) Glucan?
The cell wall of A. fumigatus, the most prevalent respiratory human fungal pathogen, is a complex and dynamic structure that is a major source of pathogen-associated molecular patterns (PAMP). α-(1,3)-Glucan is the key amorphous polysaccharide in the cell wall of A. fumigatus, accounting for 35% to 40% of the mycelial cell wall. In A. fumigatus, α-1,3 glucan is synthesized by three α-1,3 glucan synthases (Ags1p, Ags2p, and Ags3p), which are extremely high molecular weight (>200 kDa) transmembrane enzyme. It has been reported that α-1,3-glucan is a virulence factor of A. fumigatus and that strains lacking Ags3 exhibit faster disease progression in a mouse model of aspergillosis, Ags3 affects virulence indirectly by affecting the response to environmental changes.
