Abstract: In an enzymatic synthesis of 3',3'-cGAMP, other types of cyclic dinucleotides, c-di-GMP and c-di-AMP, are produced as by-products. One problem to be solved in order to establish a practical method for enzymatic synthesis of 3',3'-cGAMP is suppression of production of these other types of cyclic dinucleotides during the synthesis. As a result of intensive studies, the inventors of the present invention found a variation of 3',3'-cGAMP synthase by which the production of c-di-GMP and c-di-AMP is suppressed, and established a 3',3'-cGAMP enzymatic synthesis system using this variation of the enzyme to complete the present invention. This enzyme brings about significantly reduced production of c-di-GMP and c-di-AMP, compared to the wild-type 3',3'-cGAMP synthase. Accordingly, a production method using this enzyme makes it possible to reduce the production of other types of cyclic dinucleotides in comparison to conventional enzymatic synthesis methods, and efficiently synthesize 3',3'-cGAMP.
