Extended Data Fig. 6: Mass spectrometry data for VnOptS cyclic dinucleotides.
From: The Panoptes system uses decoy cyclic nucleotides to defend against phage

(a–c) MS spectra of chemical standard (bottom) and the VnOptS nucleotide-dependent product (top) for 2′,3′-c-di-AMP, 3′,2′-cGAMP, and 3′,2′-cUAMP. (d–e) Chemical structure of 3′,2′-cyclic guanosine monophosphate-adenosine monophosphate (3′,2′-cGAMP) and 3′,2′-cyclic uridine monophosphate-adenosine monophosphate (3′,2′-cUAMP).
