METHOD OF PREPARING CYCLIC ADENOSINE MONOPHOSPHATE

摘要

The present invention provides a method of preparing cyclic adenosine monophosphate, which includes the use of Arthrobacter sp. as an engineering bacterium, and the addition of precursors, inhibitors of glycolytic pathway and/or activators of tricarboxylic acid cycle into a fermentation medium, so as to acquire the cyclic adenosine monophosphate by fermentation. Further provided is a use of precursors, inhibitors of glycolytic pathway and/or activators of tricarboxylic acid cycle for preparing cyclic adenosine monophosphate by Arthrobacter sp.. The present invention inhibits the excessive glycolysis, increases the flux of pentose phosphate pathway, and enhances the tricarboxylic acid cycle by the addition of precursors, inhibitors of glycolytic pathway and/or activators of tricarboxylic acid cycle, so as to redistribute rationally the metabolic flux of central metabolic pathways, make the carbon flux more efficiently direct to the target product - cyclic adenosine monophosphate, and synthesize cyclic adenosine monophosphate by using carbon source efficiently.
