METHOD FOR PRODUCING PURINE NUCLEOSIDES AND NUCLEOTIDES BY FERMENTATION USING A BACTERIUM BELONGING TO THE GENUS ESCHERICHIA OR BACILLUS |
摘要 |
A method is provided for producing a purine nucleoside, such as inosine and guanosine, and a method for producing a 5'-purine nucleotide such as 5'-inosinic acid or 5'-guanylic acid, using a bacterium belonging to the either genus Escherichia or genus Bacillus, wherein purine nucleoside productivity of said bacterium is enhanced by enhancing an activity of a protein encoded by the yeaS (leuE) gene.
