    Abstract: An acid-resistant peptide solubility tag (an “inclusion body tag”) is provided that is effective in producing peptides of interest in an insoluble form. Fusion peptide constructs comprising the inclusion body tag fused to a peptide of interest are provided. An acid cleavable peptide moiety separates the inclusion body tag from the peptide of interest so that acid hydrolysis can be used during subsequent processing steps to separate the tag from the desired peptide of interest. The present inclusion body tag's resistance to acid hydrolysis facilitates easier and cleaner separation of the peptide of interest after acid hydrolysis. Specifically, a ketosteroid isomerase-derived inclusion body tag is provided that has been engineered to be more resistant to acid hydrolysis.

  • Publication number: 20100249220
    Abstract: A chimeric transactivator comprises a transcription activation domain, a repressor protein DNA binding domain and the bacterial DNA gyrase B subunit. A target gene is operatively linked to operator DNA sequences recognized by the repressor binding domain. The addition of the antibiotic coumermycin results in a coumermycin-switched dimerization of the transactivator, which then binds to operator DNA sequences and activates transcription of the target gene. The addition of novobiocin switches off expression of the target gene by abolishing coumermycin-induced dimerization of the transactivator.

A method for obtaining cells involves preparing organ-related cells which are immortalized by transferring the first gene complex and immunomodulated by transferring the second gene complex.

  • Publication number: 20090305351
    Abstract: The present invention relates to a method for producing a recombinant protein capable of increasing expression rate of a target protein and also improving solubility and folding of the expressed target protein using a modified protein disulfide isomerase (PDI) as a fusion partner, and an expression vector containing the modified PDI gene as a fusion partner. The method for preparing a recombinant protein using a modified PDI as a fusion partner according to the present invention may solve the problems concerning a low yield and solubility and folding that conventional fusion partners have, and be widely used for protein drug and industrial protein production.

  • Patent number: 7622284
    Abstract: The present invention relates to host cells transformed with a nucleic acid sequence encoding a eukaryotic xylose isomerase obtainable from an anaerobic fungus. When expressed, the sequence encoding the xylose isomerase confers to the host cell the ability to convert xylose to xylulose which may be further metabolised by the host cell. Thus, the host cell is capable of growth on xylose as carbon source. The host cell preferably is a eukaryotic microorganism such as a yeast or a filamentous fungus. The invention further relates to processes for the production of fermentation products such as ethanol, in which a host cell of the invention uses xylose for growth and for the production of the fermentation product. The invention further relates to nucleic acid sequences encoding eukaryotic xylose isomerases and xylulose kinases as obtainable from anaerobic fungi.
