This domain is found Cyclic GMP-AMP synthase from Vibrio cholerae (DncV), a prokaryotic cGAS-like enzyme that synthesises cyclic GMP- AMP (c-GAMP) and stimulates intestinal colonization. DncV adopts a structure and topology that are typical of the nucleotidyltransferase superfamily. It is organised into two domains: an N-terminal domain that contains the catalytic loop (Pfam:PF21654) and a C- terminal helix bundle that consists of eight helices and one pair of anti-parallel beta-sheets (this entry) [1-3].

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.	Domain
