  • Transcriptional regulatory DNA sequence elements and signal peptide sequence of the Coriolus hirsutus phenoloxidase gene, and plasmid vectors and transformants utilizing such sequences
    Patent number: 6075138
    Abstract: This invention relates to a novel DNA or a derivative thereof concerning the expression and secretion of a phenoloxidase gene originating in a basidiomycete (particularly a white rot fungus such as, for example Coriolus hirsutus IFO 4917) possessing the ability to produce and secrete a phenoloxidase, a novel organism containing the DNA and a protein-coding DNA, and a method for the production of proteins by the use of the novel organisms. The aforementioned "DNA concerning expression" generally refers as to a region existent on the upstream side of a structural gene and necessary for the initiation of transcription (promoter) and to a region existent on the downstream side thereof and necessary for the termination of the transcription (poly A signal or terminator), for example. The "DNA concerning secretion" generally refers to a DNA which codes a signal peptide.
