  • Enzyme with endoglucanase activity
    Patent number: 5723328
    Abstract: An enzyme from Aspergillus aculeatus exhibiting endoglucanase activity, which enzyme is designated EG II or EG IV and is encoded by a DNA sequence comprising at least one of the partial sequences shown in SEQ ID NO: 17, 18, or 19. The enzyme may be produced by recombinant DNA techniques and may be used for degradation of plant cell wall material.
    Type: Grant
    Filed: May 26, 1995
    Date of Patent: March 3, 1998
    Assignee: Novo Nordisk A/S
    Inventors: Henrik Dalboege, Lene Nonboe Andersen, Lene Venke Kofod, Markus Sakari Kauppinen, Stephan Christgau
  • Enzyme exhibiting pectin methylesterase activity
    Patent number: 5707847
    Abstract: An enzyme exhibiting pectin methyl esterase activity, wherein the enzyme a) is derived from Aspergillus aculeatus; b) is encoded by Seq ID No:1; or c) has the amino acid sequence of Seq ID No:2 or a sequence which is at least 95% homologous thereto. An enzyme can be used for the modification of plant cell wall components.

  • Enzymes with xylanase activity from Aspergillus aculeatus
    Patent number: 5693518
    Abstract: An enzyme exhibiting xylanase activity, which enzyme is immunologically reactive with an antibody raised against a purified xylanase derived from Aspercgillus aculeatus, CBS 101.43. The enzyme may be used for degrading plant cell wall components, e.g., in the preparation of feed, in baking, in the paper and pulp industry and in connection with separation of wheat into starch and gluten.
