Fermentative Accumulation of Guanosine Polyphosphate by Brevibacterium ammoniagenes

摘要

Guanosine-3′-diphosphate-5′-monophosphate (3.35 mg/ml), guanosine-3′-diphosphate-5′-diphosphate (MSI) (5.21 mg/ml), and guanosine-3′-diphosphate-5′ triphosphate (MSII) (0.82 mg/ml), in addition to guanosine 5′-monophosphate, guanosine 5′-diphosphate, and guanosine 5′-triphosphate, were accumulated by microbial conversion of 5′-xanthylic acid with a mutant of Brevibacterium ammoniagenes.
