ChEBI

Definition : A mannose-containing polysaccharide that is a major energy reserve in Leishmania. It is comprised of linear chains of beta-1,2-linked mannose residues (2-60 residues in length depending on development stage).

Definition : A melanin pigment produced by certain fungi. It plays important roles in UV protection, oxidative stress and pathogenesis. In Aspergillus fumigatus, it is used as a virulence factor and plays an important role in the survival of the fungus during unfavorable conditions both in vivo and in vitro, and protects it from the host immune system. The pigment is generally synthesised from the pentaketide pathway in which 1,8-dihydroxynaphthalene is the immediate precursor which is polymerized to 1,8-dihydroxynaphthalene-melanin by a laccase enzyme.

Definition : An exopolysaccharide composed of alpha1right4 linked galactose and alpha1right4 linked N-acetylgalactosamine (GalNAc) residues where both monosacharides are randomly distributed. It is secreted by the opportunistic fungal pathogens, Aspergillus fumigatus and Aspergillus niger.

Definition : A glycolipid comprising a glycosylphosphatidyl-myo-inositol-anchored lipoglycan; a virulence factor associated with Mycobacterium tuberculosis.
