  • Fungal promoters active in the presence of glucose
    Patent number: 6011147
    Abstract: A method is described for the identification and cloning of promoters that express under a defined environmental condition, such as growth in glucose medium. Using this method, five Trichodermal promoters capable of the high expression of operably linked coding sequences are identified, one of which is the promoter for T. reesei tef1. Also provided are altered cbh1 promoters, altered so that glucose no longer represses expression from such promoter. The invention further provides vectors and hosts that utilize such promoters, and unique fungal enzyme compositions from such hosts.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: January 4, 2000
    Assignee: Rohm Enzyme Finland Oy
    Inventors: Tiina Hannele Nakari, Maija-Leena Onnela, Marja Hannele Ilmen, Kaisu Milja Helena Nevalainen, Merja Elisa Penttila
  • Promoters and uses thereof
    Patent number: 6001595
    Abstract: Shortened sophorose inducible promoters are provided. The invention further provides vectors containing such promoters hosts transformed with the same, and methods utilizing such promoters for the expression of operably linked sequences.
    Type: Grant
