Abstract:
A process for producing 5â€²-inosinic acid or 5â€²-guanylic acid, which comprises contacting inosine or guanosine or a precursor thereof with a transformant obtained by introducing a gene encoding a protein comprising SEQ ID NO: 3 or 17 having inosine-guanosine kinase activity into microorganism capable of regenerating ATP consumed in the process, an energy source and a phosphate group donor, accumulating 5â€²-inosinic acid or 5â€²-guanylic acid in the reaction solution, and collecting the same therefrom, where the phosphate group donor is an inorganic phosphoric acid, a salt of an inorganic phosphoric acid, phenyl phosphate, acetyl phosphate or carbamyl phosphate.
