  • Patent number: 7910344
    Abstract: Extracellular tyrosinases obtainable from Trichoderma spp. and methods for producing them by recombinant technology. The enzymes are particularly useful in cross-linking food proteins.
    Type: Grant
    Filed: February 9, 2006
    Date of Patent: March 22, 2011
    Assignee: Valtion teknillinen tutkimuskeskus

  • Patent number: 7816129
    Abstract: The present invention is related to an improved production of bacterial proteins in filamentous fungus, e.g. in Trichoderma and Aspergillus. The improvement is achieved by constructing expression vectors, which comprise the bacterial protein encoding DNA sequences fused in frame with a DNA sequence encoding a filamentous fungus secretable protein or one or more functional domains of said protein. Filamentous fungus hosts transformed with such expression vectors secrete the desired proteins or enzymes, especially xylanases or cellulases originating from bacteria or more preferably from actinornycetes into the culture medium of the host. The desired proteins or enzymes can be used directly from the culture medium after separation of host cells or recovered and treated using down-stream processes, which are appropriate for the respective application. Xylanases or cellulases from actinomycetes produced using the above expression vectors are most suitable for treating plant derived materials e.g.

  • Publication number: 20090053364
    Abstract: Low-ingredient meat products, which contain a reduced amount of salt, phosphate and/or meat, generally have poor texture and water-binding properties. The texture and water binding of such a product may be significantly improved with tyrosinase, which is a protein cross-linking enzyme. The invention is directed to a method of preparing a low-ingredient meat product by adding tyrosinase, and to a low-ingredient meat product modified by tyrosinase.

  • Patent number: 7348172
    Abstract: The invention is related to a method and DNA constructs for obtaining in a filamentous fungus host a higher production level of a carbohydrate degrading (CD) enzyme, having in its original state a catalytic module (CAT) and a carbohydrate binding module (CBM) separated by a linker region. The DNA construct comprising a truncated actinomycetes, preferably Nonomuraea flexuosa (NJ) derived DNA sequence encoding a truncated form of the CD enzyme, for example Nf Xyn11A, Nf Xyn10A, and is introduced into a filamentous fungal host. Said CD enzyme contains the catalytically active region of CAT but lacks part or all of the CBM, or all of the CBM and part or all of the linker region and is expressed and secreted under the control of regulatory sequences comprising at least a signal sequence, but also promoters, terminators and DNA sequences encoding a secretable carrier protein or domains thereof, preferably originating from filamentous fungi are included.
