  • .DELTA..sup.5,7 -sterol reductase from arabidopsis thaliana
    Patent number: 5759801
    Abstract: A nucleic acid sequence containing a sequence coding for a protein having a delta-5,7 sterol, delta-7 reductase activity, said nucleic acid being a DNA or an RNA, production process, strains of transformed yeasts and uses thereof.
    Type: Grant
    Filed: February 12, 1996
    Date of Patent: June 2, 1998

  • Yeast strains with stable integration of heterologous genes
    Patent number: 5635369
    Abstract: Yeast strains and a method of expression in yeast of the monooxygenase activity of heterologous cytochromes P450 are disclosed. Within the genome of the yeast strain, genes for NADPH-cytochrome P450 reductase and cytochrome b5 are stably integrated and coexpressed. The genome is transformed with a plasmid carrying a cassette for the expression of a heterologous P450 gene.
