Bacterial ribonucleoprotein bodies maintain an acidic pH environment as a mechanism of enzyme regulation

Phase separated biomolecular condensates create subcellular niches, yet their role in client regulation remains unclear. Here, we demonstrate that Bacterial Ribonucleoprotein bodies (BR-bodies) are acidic. Using ratiometric fluorescent probes in vivo, we find BR-bodies exhibit a dense-phase pH of ∼5.1, significantly lo...
