Nucleotide synthetase enzyme of the DNA polymerase beta superfamily. Experimental studies have demonstrated cGAMP synthetase activity in the Vibrio cholerae DncV protein, a member of the SMODS family. The diversity inherent to the SMODS family suggests members of the family could generate a range of nucleotides, cyclic and/or linear. The nucleotide second messengers generated by the SMODS domains are predicted to activate effectors in a class of conflict systems reliant on the production and sensing of the nucleotide second messengers [1] [2].
