Thermally induced transcription of the phoU gene under control of the major leftward promoter, pL, of phage lambda resulted in production of the PhoU protein to compose approximately 5% of the total cell protein. The PhoU protein was present in the cytoplasm in the form of an aggregate. The amino acid composition and N-terminal amino acid sequence of the purified protein confirmed the reading frame established earlier for the phoU gene.

" Accumulibacter" is a unique and pivotal genus of polyphosphate-accumulating organisms prevalent in wastewater treatment plants and plays mainstay roles in the global phosphorus cycle. However, the efforts to fully understand their genetic and metabolic characteristics are largely hindered by major limitations in existing sequence-based annotation methods. Here, we reported an integrated approach combining pangenome analysis, protein structure prediction and clustering, and meta-omic characterization, to uncover genetic and metabolic traits previously unexplored for .

PhoU proteins are negative regulators of the phosphate response, regulate virulence, and contribute to antibiotic resistance. has multiple genes encoding PhoU homologs that regulate persister formation and potentially virulence, but the molecular mechanisms of this regulation are not fully understood. We used a bacterial adenylate cyclase two-hybrid system to assess interactions between PhoU homologs and other proteins known to interact with PhoU from PhoU (also referred to as PhoU1) interacted with PhoU itself; PitR (also referred to as PhoU2) interacted with PitR itself.

Accumulibacter, a prominent polyphosphate-accumulating organism (PAO) in wastewater treatment, plays a crucial role in enhanced biological phosphorus removal (EBPR). The genetic underpinnings of its polyphosphate accumulation capabilities, however, remain largely unknown. Here, we conducted a comprehensive genomic analysis of .

Multimodal treatment of cancer is an unstoppable revolution in clinical application. However, designing a platform that integrates therapeutic modalities with different pharmacokinetic characteristics remains a great challenge. Herein, we designed a universal lipid nanoplatform equipping a ROS-cleavable docetaxel prodrug (DTX-L-DTX) and an NF-E2-related factor 2 (NRF2) inhibitor (clobetasol propionate, CP).

Bacteria acquire P primarily as inorganic orthophosphate (Pi, PO). Once internalized, Pi is rapidly assimilated into biomass during the synthesis of ATP. Because Pi is essential, but excessive ATP is toxic, the acquisition of environmental Pi is tightly regulated.
