For other salt forms please inquire. Cyclic oligoadenylates were found to be novel bacterial second messengers involved in the Type III CRISPR-Cas-associated detection and degradation of invasive genetic elements in many prokaryotes. The Streptococcus thermophilus type III-A CRISPR-Cas system produces c-pentaAMP as well as a range of differently sized cyclic oligoadenylates both in vitro and in vivo, although only the least abundant c-hexaAMP (Biolog Cat. No. C 332) activated the Csm6 ribonuclease of this organism. Reference: Smalakyte et al., Nucleic Acids Res., 48, 9204 - 9217 (2020).
