In bacteria, cCMP and cUMP have a key role in defense against infection with bacterial viruses. Bacteriophages encode phosphodiesterases (PDEs; 'nucleases'; Apyc1), which cleave cCMP/cUMP, counteracting this defense. We propose that PDEs are of broader biological relevance, including cCMP/cUMP-cleaving PDEs of eukaryotic viruses, which may constitute new drug targets.
在细菌中，cCMP 和 cUMP 在防御细菌病毒感染方面起着关键作用。噬菌体编码磷酸二酯酶（PDEs；核酸酶；Apyc1），可切割 cCMP/cUMP，从而破坏这种防御。我们提出 PDEs 具有更广泛的生物学意义，包括真核病毒的 cCMP/cUMP 裂解 PDEs，它们可能成为新的药物靶点。
