PRODUCTION METHOD AND PRODUCTION INTERMEDIATE FOR GUANOSINE-3',5'-BISDIPHOSPHATE

The present invention relates to a production method and a production intermediate for guanosine-3′,5′-bisdiphosphate. 4. The production method according to any one of to , wherein Rand Reach represents methyl , Rrepresents tert-butyl , and Rand Reach represents benzyl.6. The production method according to claim 5 , wherein Rand Reach represents 2-cyanoethyl claim 5 , and Rrepresents N═CH—N(CH). The present invention relates to a production method and a production intermediate for guanosine-3′,5′-bisdiphosphate (hereinafter also referred to as “ppGpp”).Microbes such as bacteria have a mechanism for controlling an in vivo reaction as a way to defuse crisis situations of life due to an amino-acid deficiency state. Such a mechanism is called a stringent response, and it is known that a central molecule of the stringent response mechanism is ppGpp.The synthesis of ppGpp in microbes is catalyzed by two enzymes called RelA and SpoT. These enzymes synthesize ppGpp by transferring a pyrophosphoric acid at a βγ position of ATP to GTP or a 3′ terminal of GDP. The biosynthesized ppGpp inhibits transcription, translation, replication, and biosynthesis of GTP in the microbes and functions to suppress wasteful energy consumption until the amino-acid deficiency state is eliminated. Since amino-acid synthases are not inhibited, amino acids are gradually stored in the microbes. When the starvation state is broken, the synthesis of ppGpp is suppressed, and the in vivo reaction is restored. The RelA protein only has synthetic activity of ppGpp, whereas the SpoT protein has synthetic activity and decomposition activity of ppGpp and plays a role in degradation of ppGpp after the starvation state is broken.Recently, it has become obvious that ppGpp functions also in plant growth (NPL 1 and NPL 2). The action of ppGpp in higher organisms is an interesting object that should be studied in the future.Although ppGpp is commercially available, the supply of ppGpp is mainly performed by enzyme ...
