Polysaccharides found in some Daemonorops species are known for their medicinal anticoagulant properties.
The approximate molecular weight of PSK is 100,000 Da, and the protein component is reported at the β-1,6 side chain.
2-Epimerase was discovered as a target because it was one of the enzymes in the biosynthetic pathway for synthesizing an essential neutral polysaccharide in the cell wall of B. anthracis (Glu:Gal-NAc:Man-NAc at a 3:2:1 ratio).
Schizophyllan (Sonifilan, SPG) is a neutral extracellular polysaccharide produced by the fungus Schizophyllum commune.
