  "summary": "Ceg14 is a Legionella pneumophila effector whose enzymatic activity is activated by host actin and inhibited by the cognate metaeffector AnkJ. Recent studies established that Ceg14 cleaves ATP to AMP and pyrophosphate and can transfer AMP to 3-phosphoglycerate, but how actin and AnkJ regulate these catalytic states remained unclear. Here, we show that Ceg14 is selectively activated by G-actin and…",
