  • Diguanylate cyclase method of producing the same and its use in the manufacture of cyclic-di-GMP and analogues thereof
    Patent number: 8859237
    Abstract: Described is a new stand-alone diguanylate cyclase polypeptide having a GGDEF motif and a mutated I-site that does not bind c-di-GMP. We demonstrate that the production yield of c-di-GMP and analogues was significantly increased by mutation of a conserved residue in the putative regulatory I-site.
