| additional information | overexpression of agsA in Aspergillus nidulans under the control of a constitutive promoter in the genetic background of agsB disruptants, the native promoter is replaced by the constitutive tef1 promoter. Alkali-soluble glucan from the agsA overexpressing strain is composed mainly of alpha-1,3-glucan. The agsA gene is disrupted by using the Cre/loxP marker recycling system.

| malfunction | the disruption of the agsA gene does not alter or slightly increase the alpha-1,3-glucan content compared to wild-type. Overexpression of agsA increases the amount of alkali-soluble glucan compared to wild-type. Alkali-soluble glucan from the agsA overexpressing strain is composed mainly of alpha-1,3-glucan (1,3,5-triacetyl-2,4,6-tri-O-methyl-D-glucitol). The average molecular mass of alkali-soluble glucan is larger in agsA overexpressing than in agsB overespressing strains. The double mutant DELTAagsA-DELTAagsB strain lacks cell wall alpha-1,3-glucan | Aspergillus nidulans |
| malfunction | the disruption of the agsB gene leads to loss of alpha-1,3-glucan. Overexpression of agsA increases the amount of alkali-soluble glucan compared to wild-type. Alkali-soluble glucan from the agsB overexpressing strain is composed mainly of alpha-1,3-glucan (1,3,5-triacetyl-2,4,6-tri-O-methyl-D-glucitol).

| physiological function | alpha-1,3-glucan is one of the main polysaccharides in the cell wall of filamentous fungi. Aspergillus nidulans has two alpha-1,3-glucan synthase genes, agsA and agsB. AgsB is a major alpha-1,3-glucan synthase in vegetative hyphae, but the function of AgsA is intracellular | Aspergillus nidulans |
