Glycosidases of Aspergillus niger
A highly purified preparation of 1,2-oc-L-fucosidase, free of /3-galactosidase and P-N-acetylglucosaminidase activities, has been obtained from a commercial preparation of Aspergillus niger by a simple isolation procedure involving ammonium sulfate precipitation, pressure dialysis, repeated gel Cltration on Sephadex G-150, and chromatography on diethylaminoethyl Sephadex A-50. The enzyme has a ...
متن کاملDegradation of pectic polysaccharides in various fruits by pectinase derived from Aspergillus niger
Aspergillus spp. are widely spread plant pathogens. In several kinds of fruit, especially in apple and peach, aspergillus rot is one of the postharvest desease in fruit, but the infection mechanism is not known. The degradation of cell walls by pathogens is significant in primary infection and afterinfection, and plays an important role in the advancement of mycelium into the host plant and the...

متن کاملLysine aminopeptidase of Aspergillus niger.
Conserved regions within the M1 family of metallo-aminopeptidases have been used to clone a zinc aminopeptidase from the industrially used fungus Aspergillus niger. The derived amino acid sequence of ApsA is highly similar to two yeast zinc aminopeptidases, LAPI and AAPI (53.3 and 50.9% overall similarity, respectively), two members of the M1 family of metallo-aminopeptidases. The encoding gene...
