This is the nucleotidyltransferase domain of DncV from Vibrio cholerae (also known as Cyclic GMP-AMP synthase) and related proteins [1-4]. DncV catalyses the synthesis of 3'3'-cyclic GMP-AMP (3'3'-cGAMP) from GTP and ATP. It is part of the CBASS (cyclic oligonucleotide-based antiphage signaling system) which provides immunity against bacteriophage [1-4]. This protein is required for efficient V.cholerae intestinal colonization and and down-regulates the colonization-influencing process of chemotaxis.
