A PROCESS FOR PREPARING A 5''-NUCLEOTIDE HAVING A DESIRED PURINE OR PYRIMIDINE BASE COMPONENT, WHICH COMPRISES CONTACTING AN ENZYME SORCE WITH AN AQUEOUS MEDIUM CONTAINING THE ORGANIC BASE CORRESPONDING TO THE DESIRED BASE COMPONENT AND A 5''-NUCLEOTIDE OTHER THAN THAT TO BE PREPARED AND HAVING A BASE COMPONENT SELECTED FROM THE GROUP CONSISTINGD OF A PURINE AND PYRIMIDINE WHICH IS DIFFERENT FROM SAID DESIRED BASE COMPONENT UNTIL THE DESIRED 5''-NUCLEOTIDE IS FORMED; AND RECOVERING THE FORMED 5''-NUCLEOTIDE, SAID ENZYME SOURCE BEING CAPABLE OF PRODUCING A 5''-NUCLEOTIDE SELECTED FROM THE GROUP CONSISTING OF ADENYLIC ACID AND INOSINIC ACID WHEN IN CONTACT WITH AN AQUEOUS SOLUTION CONTAINING 0.135 G. ADENINE AND 1.43 G. DISODIUM-5''- URIDYLATE AT 40*C. FOR A PERIOD OF 3 TO 20 HOURS AT PH 8 TO 9, SAID ENZYME SOURCE BEING PREPARED FROMS A MICROORGANISM SELECTED FROM THE GENERA ALCALIGENES, ESCHERICHIA, AEOBACTER, PSEUDOMONAS, STAPHYLOCOCCUS, SERRATIA, FLAVOBACTERIUM, PROTEUS, AND MICROCOCCUS.
