  • MUTANT ARABINOSE PROMOTER FOR INDUCIBLE GENE EXPRESSION
    Publication number: 20100068758
    Abstract: An L-arabinose inducible expression system comprising a mutant arabinose promoter. This system exhibits an increase in heterologous protein production upon induction with L-arabinose and comprises a mutant araB promoter and an AraC transcription binding region. This system retains the tight regulatory control characteristic of the wild type arabinose operon.

  • FERMENTIVE PRODUCTION OF FOUR CARBON ALCOHOLS
    Publication number: 20070259410
    Abstract: Methods for the fermentive production of four carbon alcohols are provided. Specifically, butanol, preferably 2-butanol is produced by the fermentive growth of a recombinant bacteria expressing a 2-butanol biosynthetic pathway. The recombinant microorganisms and methods of the invention can also be adapted to produce 2-butanone, an intermediate in the 2-butanol biosynthetic pathways disclosed herein.

  • Method for the production of resveratrol in a recombinant bacterial host cell
    Publication number: 20070031951
    Abstract: A method to produce resveratrol in a recombinant bacterial host cell is provided. Expression of a resveratrol synthase gene in combination with genes involved in the phenylpropanoid pathway enabled recombinant microbial production of resveratrol.

  • DNA and amino acid sequence of a tyrosine ammonia lyase enzyme from the bacterium
    Patent number: 7067302
    Abstract: A novel tyrosine ammonia lyase enzyme was identified in the bacterium Rhodobacter sphaeroides. This enzyme has a higher activity for tyrosine than for phenylalanine and is useful for the production of para-hydroxycinnamic acid directly from tyrosine. The gene encoding this enzyme was cloned by direct amplification using the genomic DNA and was expressed in E. coli.
