PG - 2259-61 AB - Guanosine 5'-monophosphate (5'-GMP) and inosine 5'-monophosphate (5'-IMP) are widely used as flavor enhancers. Recently, a novel process for 5'-IMP production by phosphorylation of inosine using guanosine-inosine kinase coupled with ATP regeneration was reported. In this study, we demonstrated the practical possibility of producing 5'-GMP by phosphorylation of guanosine using a guanosine-inosine kinase from Exiguobacterium acetylicum coupled with ATP regeneration.
