Patents by Inventor Robert S. Daves

Robert S. Daves has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hybrid yeast promoter comprising an ENO2 UAS and TATA region and an additional UAS located between said ENO2 UAS and TATA region
    Patent number: 5541084
    Abstract: A DNA sequence having a yeast ENO2 promoter functionally fused to a heterologous gene.
    Type: Grant
    Filed: June 12, 1992
    Date of Patent: July 30, 1996
    Assignee: Robert R. Yocum
    Inventors: Scott Van Arsdell, Robert S. Daves, Robert R. Yocum
  • Industrial yeast comprising an integrated glucoamylase gene
    Patent number: 5422267
    Abstract: A vector having a gene for resistance to an antibiotic otherwise capable of killing a host yeast cell, the gene being transcribed from a yeast promoter sequence and the vector being capable of being integrated into a chromosome of the host yeast cell; and a diploid or greater ploidy yeast cell transformed by such a vector with heterologous DNA.
    Type: Grant
    Filed: January 24, 1990
    Date of Patent: June 6, 1995
    Assignee: Robert R. Yocum
    Inventors: Robert R. Yocum, Robert S. Daves, Michael C. Chen
  • Expression and secretion vector for yeast containing a glucoamylase signal sequence
    Patent number: 5024941
    Abstract: A vector including a DNA sequence encoding a secretory signal sequence substantially identical to the secretory signal-encoding sequence of a glucoamylase gene from Saccharomyces diastaticus or S. cerevisiae; and upstream from the signal-encoding sequence, a DNA sequence capable of promoting transcription in yeast (e.g., a high yield promoter, such as the promoter of the triose phosphate isomerase gene), transcription of the signal-encoding sequence being under the control of the transcription-promoting sequence, a site for the insertion into the vector of a heterologous DNA sequence, in reading frame with the signal-encoding sequence. The vector is useful as an expression vector in yeast.
