Zusammenfassung: | The invention provides a gene-expressing system of non-pathogenic bacteria for metabolizing tyrosine, in which the gene-expressing system includes a first nucleic acid fragment and a second nucleic acid fragment operably connecting to the first nucleic acid fragment. The aforementioned first nucleic acid fragment and the second nucleic acid fragment have sequences shown in sequence identity number (SEQ ID NO.): 1 and 2, respectively. A transformed strain having the gene-expressing system reduced the amount of tyrosine by converting tyrosine into p-coumaric acid, thereby reducing the amount of uremic toxins. |
