  • Patent number: 8642290
    Abstract: The present invention relates to functional cDNA and genomic sequences encoding PrtT proteins, which are transcriptional activity on a protease promoter, to PrtT proteins and their uses. The invention further relates to two distinct types of filamentous fungal cells. Filamentous fungal cells are transformed to over-express these PrtT proteins: this type of filamentous fungus will be highly suited as protease producer. Alternatively, the endogenous prtT genes of filamentous fungal cells are inactivated: this type of filamentious fungus is highly suited for the production of any polypeptide native or not which is highly sensitive for protease degradation. The PrtT proteins of the invention provide means for identification of functional homologues in other species.
