METHOD OF OBTAINING NUCLEIC ACIDS

摘要

A process for producing 5'-inosinic acid or 5'-guanylic acid usable in seasonings, etc. from inosine or guanosine or precursors thereof by using a microorganism which carries a DNA encoding a protein having the activity of forming 5'-inosinic acid or 5'-guanylic acid from inosine or guanosine and is capable of reproducing adenosine triphosphate (ATP); a novel protein having an inosine-guanosine kinase activity; a gene encoding this protein; a recombinant DNA containing this gene; and a microorganism transformed thereby.
