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′) …
