A. fumigatus Galactomannan Production Service
Galactomannan Biosynthesis of the Cell Wall in A. fumigatus
Galactomannan produced by the human fungal pathogen A. fumigatus is an iconic biomarker including mannose and galactofuranose. Galactomannan produced by A. fumigatus is a unique fungal polysaccharide that contains three forms: membrane-bound via GPI anchors, cell wall-localized galactomannan, and free galactomannan. The biosynthetic pathway of galactomannan in A. fumigatus requires four steps: (1) Synthesis and transport of nucleotide sugars; (2) Polymerization of galactomannan through glycosyltransferase; (3) Transport of lipo-galactomannan to the surface of the plasma membrane within the cell; (4) Cross-link galactomannan to β-1,3-glucan in the cell wall. In addition, galactomannan is one of the key antigenic molecules of A. fumigatus, which is of great significance for the diagnosis of invasive bronchial disease.
