  • Patent number: 5895747
    Abstract: The Tax protein of Human T Cell Leukemia Virus Type 1 (HTLV-I) transcriptionally activated the HTLV-I promoter through binding sites for ATF, a family of cellular bZIP transcription factors. In this disclosure, it is reported that Tax dramatically increases the in vitro DNA binding activity of multiple ATF proteins. Tax also stimulates DNA binding of related bZIP proteins but does not affect the activity of proteins lacking a bZIP domain. The increased DNA binding activity occurs by a novel mechanism in which Tax promotes homodimerization in the absence of DNA. The elevated concentration of the bZIP homodimer results in increased DNA binding.

    Abstract: A process for expression of a protein product in Aspergillus oryzae is disclosed. The process comprises transforming Aspergillus oryzae with a vector system comprising DNA-sequences encoding functions facilitating gene expression, a suitable marker for selection of transformants, and a DNA-sequence encoding the desired protein product. The process enables industrial production of many different polypeptides and proteins in A. oryzae. Examples of such products are chymosin or prochymosin and other rennets, proteases, lipases and amylases. Also disclosed is an effective promoter for expression of a protein in Aspergillus. A preferred promoter is the TAKA-amylase promoter or functional parts thereof. There is also provided a process for the production of a recombinant Humicola lipase. The recombinant Humicola lipase from A. oryzae differs from the native lipase in having a greater glycosylation and in exhibiting an improved thermostability.
