The paper identifies 7 novel polyP-binding proteins in E. coli linked to translation control and ribosome biogenesis, with specific roles for YihI and Rnr.

The paper uses proteomics to show that E. coli polyphosphate kinase (PPK) regulates lipid A modifications and polymyxin resistance during starvation by affecting the BasS/BasR two-component system.

The paper investigates how Ddp1 and Ppx1 counter polyphosphate toxicity in yeast by analyzing stress responses and enzyme functions.

The paper identifies human biological processes and protein sequence motifs potentially targeted by SARS-CoV-2 using PPI networks and computational methods.

This study shows that internally produced polyP in human cells activates signaling pathways and alters gene and protein expression through ectopic expression of a bacterial polyP synthetase.
