  • Publication number: 20060275881
    Abstract: Genes encoding phenylalanine ammonia-lyase (PAL), tyrosine ammonia lyase (TAL) and phenylalanine hydroxylase (PAH) have been introduced into a host organism for the production of Para-hydroxycinnamic acid (PHCA). The introduction of these genes results in the redirection of carbon flow in the host, optimizing the flow of carbon from glucose to PHCA. The intermediates, tyrosine and cinnamic acid are also produced.

  • Publication number: 20040014085
    Abstract: A method for the recombination of a gene is disclosed. The method involves the design of unpaired forward and reverse primers having homology to the 5′ end of one template and to the 3′ end of another template. Short primer extension periods results in a recombined template having paired 5′ and 3′ ends that can then be amplified. The amplified sample is devoid of any parental template.

  • Publication number: 20030170834
    Abstract: The present invention provides several methods for biological production of para-hydroxycinnamic acid (PHCA). The invention is also directed to the discovery of new fungi and bacteria that possess the ability to convert cinnamate to PHCA. The invention relates to developing of a new biocatalyst for conversion of glucose to PHCA by incorporation of the wild type PAL from the yeast Rhodotorula glutinis into E. coli underlining the ability of the wildtype PAL to convert tyrosine to PHCA. The invention is also directed to developing a new biocatalyst for conversion of glucose to PHCA by incorporation of the wildtype PAL from the yeast Rhodotorula glutinis plus the plant cytochrome P-450 and the cytochrome P-450 reductase into E. coli. In yet another embodiment, the present invention provides for the developing of a new biocatalyst through mutagenesis of the wild type yeast PAL which possesses enhanced tyrosine ammonia-lyase (TAL) activity.
