  • DNA comprising regulatory regions from gene y of penicillium chrysogenum
    Patent number: 5747285
    Abstract: A gene expression system and a protein secretion system for eukaryotic, especially fungal, microorganisms has been provided for.
    Type: Grant
    Filed: March 8, 1994
    Date of Patent: May 5, 1998
    Assignee: Gist-Brocades, NV.
    Inventors: Roelof Ary Lans Bovenberg, Adrianus Wilhelmus Hermanus Vollebregt, Pieter Van Solingen
  • Method and compositions for enhancing production of secondary metabolites using clustered biosynthetic genes
    Patent number: 5462862
    Abstract: Clustered antibiotic biosynthetic genes are employed for improvement of production of the antibiotic in microorganisms and for the isolation of other genes involved in the biosynthesis of the antibiotic. The invention is exemplified with improved production of penicillin in Penicillium chrysogenum, with the isolation of another clustered biosynthetic gene(s) and with the expression of penicillin biosynthetic genes in Acremonium chrysogenum.
    Type: Grant
    Filed: January 25, 1993
    Date of Patent: October 31, 1995
    Assignee: Gist-brocades N.V.
    Inventors: Martinus A. M. Groenen, Annemarie E. Veenstra, Pieter Van Solingen, Bertus P. Koekman, Lucia H. M. Van Der Voort, Juan F. Martin, Santiago Gutierrez, Bruno Diez, Emilio Alvarez, Jose L. Barredo, Christina Esmahan
  • Method for identifying and using biosynthetic genes for enhanced production of secondary metabolites
    Patent number: 5108918
    Abstract: Novel methods and compositions are provided for the enhanced production of secondary metabolites. Methods are provided for identifying sequences which when transformed into secondary metabolite producing hosts, enhance the production of secondary metabolite. The process is exemplified for penicillin. In addition, the P. chrysogenum acyltransferase gene is isolated and sequenced.
