    • 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.

    • C12N9/88C07K2319/00C12N15/8243
    • The invention relates to high-level production of pHBA in green plants using a unique expression cassette. The latter comprises a chorismate pyruvate lyase (CPL) coding sequence operably linked to a suitable promoter capable of driving protein expression in higher plants. Additionally, the CPL cassette comprises a sequence encoding a chloroplast transit peptide, its natural cleavage site, and a small portion of the transit peptide donor protein fused to the N-terminus of CPL. The chloroplast targeting sequence targets the foreign protein to the chloroplast compartment and aids in its uptake into the organelle. The cleavage site is unique to the transit peptide, and cleavage of the chimeric protein encoded by the cassette at this site releases a novel polypeptide that has full enzyme activity, comprising the mature CPL enzyme and a small portion of the transit peptide donor.
    • 本发明涉及使用独特的表达盒在绿色植物中高水平生产pHBA。 后者包括可操作地连接到能够驱动高等植物中的蛋白质表达的合适的启动子的草酸丙酸裂解酶(CPL)编码序列。 此外,CPL盒包含编码叶绿体转运肽,其天然切割位点的序列和与CPL的N末端融合的转运肽供体蛋白的一小部分。 叶绿体靶向序列将外来蛋白质靶向叶绿体隔室,并有助于其吸收到细胞器中。 切割位点对于转运肽是独特的,并且在该位点处由盒编码的嵌合蛋白质的切割释放出具有完整酶活性的新型多肽,其包含成熟CPL酶和少量转运肽供体。
