The anti-inflammatory drug mesalamine targets bacterial polyphosphate accumulation
Mesalamine serves as the gold standard in treating ulcerative colitis. However, its precise
mechanism (s) of action remains unclear. Here, we show that mesalamine treatment rapidly …

Polyphosphate drives bacterial heterochromatin formation
Heterochromatin is most often associated with eukaryotic organisms. Yet, bacteria also contain
areas with densely protein-occupied chromatin that appear to silence gene expression. …
