  • Peroxidase variants with improved hydrogen peroxide stability
    Patent number: 6258769
    Abstract: A variant of a Coprinus cinereus peroxidase having one or more substitutions selected from M166L, V, I, F, Q and M242L, V, I, F, Q, wherein the parent peroxidase is encoded by the DNA sequence shown of SEQ ID:1.
    Type: Grant
    Filed: October 6, 1998
    Date of Patent: July 10, 2001
    Assignee: Novozymes A/S Patents
    Inventors: Karen Gjesing Welinder, Morten Birket Andersen
  • Process for producing heme proteins
    Patent number: 5958724
    Abstract: The present invention relates to methods for producing heterologous heme proteins extracellularly comprising transforming a filamentous fungus with a vector comprising a DNA sequence encoding the heterologous heme protein and a DNA sequence encoding a preregion permitting secretion of the expressed heme protein, and culturing the transformed filamentous fungus in a suitable culture medium to produce the heme protein.
    Type: Grant
    Filed: May 20, 1997
    Date of Patent: September 28, 1999
    Assignee: Novo Nordisk A/S
    Inventors: Henrik Dalb.o slashed.ge, Ejner Bech Jensen, Karen Gjesing Welinder
  • Peroxidase variants with improved hydrogen peroxide stability
    Patent number: 5851811
    Abstract: It has surprisingly been found that peroxidase variants with an improved stability towards hydrogen peroxide may be prepared by recombinant DNA techniques. Accordingly, the present invention relates to a peroxidase variant with improved hydrogen peroxide stability, characterized by insertion, deletion or substitution of one or more amino acid residues located in or near the substrate channel of the parent peroxidase, near the heme group of the parent peroxidase or at or near the active site of the parent peroxidase.
    Type: Grant
