  • Patent number: 5702934
    Abstract: The present invention is related to a process for producing an active enzyme comprising fermenting the proform of the active enzyme in the present of a proteolytic enzyme different from the active enzyme and capable of converting the proenzyme into an active enzyme as well as to host cells, recombinant expression vectors and host cells suitable for use in the process.

  • Patent number: 5629203
    Abstract: Efficient integration of heterologous DNA into yeast genomic DNA is accomplished at high copy number by targeting integration vectors to dispersed repetitive elements such as DELTA sequences, Ty elements, or tRNA DNA sequences present in the host cell genome.
    Type: Grant

  • Patent number: 5342921
    Abstract: Novel methods and compositions are provided for enhanced yield of heterologous proteins in fungi. The method and compositions involve employing fusion sequences involving a sequence encoding a heterologous product produced in relatively large amount as a stable polypeptide in the host fused to a second sequence in open reading frame with the prior sequence coding for a different heterologous polypeptide, where the two polypeptides are joined by a selectively cleavable linkage. In particular, a sequence coding for superoxide dismutase is joined to another polypeptide of interest at either terminus of the superoxide dismutase in a yeast expression vector under transcriptional control of an active promoter and the vector introduced into a yeast host and the host grown. High yields of the fusion product are obtained in this manner, where the fusion product can be selectively cleaved so as to produce both the superoxide dismutase and the other polypeptide in high yield.The S.

  • Patent number: 4880734
    Abstract: Methods and compositions are provided for efficient expression of genes in unicellular microoorganisms, particularly yeast. The systems involve an expression system employing transcriptional initiation regions from glycolytic enzymes, particularly a chimeric expression system, having a first region providing for regulatable or constitutive expression, a second region providing for transcriptional initiation, where regions one and two are not found joined together in functional relationship in nature, and optionally a sequence providing for a secretory leader and processing signal, where the expression cassette will be joined to a gene which may be homologous or heterologous to the host. The expression cassette can be used on an extrachromosomal element or integrated into the host genome, whereby continuous expression can be achieved or inducible expression is obtained, by virtue of the presence or absence of an inducer.
