The substrate specificity of recombinant full-length diguanylate cyclase (DGC) of Thermotoga maritima with mutant allosteric site was investigated. It has been originally shown that the enzyme could use GTP closest analogues - 2'-deoxyguanosine-5'-triphosphate (dGTP) and 9-β-D-arabinofuranosyl-guanine-5'-triphosphate (araGTP) as the substrates. The first demonstrations of an enzymatic synthesis of bis-(3'-5')-cyclic dimeric deoxyguanosine monophosphate (c-di-dGMP) and the previously unknown bis-(3'-5')-cyclic dimeric araguanosine monophosphate (c-di-araGMP) using DGC of T. maritima in the form of inclusion bodies have been provided.
