Ectopic Expression of PII Induces Stomatal Closure in Lotus japonicus

Frontiers in Plant Science, 2017
The PII protein in plants has been associated to many different tissue specialized roles concerning the Nitrogen assimilation pathways. We report here the further characterization of L. japonicus transgenic lines overexpressing the PII protein encoded by

The immunogenicity of plant-based COE-GCN4pII protein in pigs against the highly virulent porcine epidemic diarrhea virus strain from genotype 2

Frontiers in Veterinary Science, 2022
Porcine epidemic diarrhea virus (PEDV) is a serious infectious causative agent in swine, especially in neonatal piglets. PEDV genotype 2 (G2) strains, particularly G2a, were the primary causes of porcine epidemic diarrhea (PED) outbreaks in Vietnam. Here,

Structural basis for the regulation of NtcA-dependent transcription by proteins PipX and PII [PDF]

Proceedings of the National Academy of Sciences, 2010
PII, an ancient and widespread signaling protein, transduces nitrogen/carbon/energy abundance signals through interactions with target proteins. We clarify structurally how PII regulates gene expression mediated by the transcription factor NtcA, the global nitrogen regulator of cyanobacteria, shedding light on NtcA structure and ...

Effects of Inorganic Carbon Limitation on the Metabolome of the Synechocystis sp. PCC 6803 Mutant Defective in glnB Encoding the Central Regulator PII of Cyanobacterial C/N Acclimation

Metabolites, 2014
Cyanobacteria are the only prokaryotes performing oxygenic photosynthesis. Non-diazotrophic strains such as the model Synechocystis sp. PCC 6803 depend on a balanced uptake and assimilation of inorganic carbon and nitrogen sources. The internal C/N ratio

The interaction between polyphyllin I and SQLE protein induces hepatotoxicity through SREBP-2/HMGCR/SQLE/LSS pathway

Journal of Pharmaceutical Analysis, 2023
Polyphyllin I (PPI) and polyphyllin II (PII) are the main active substances in the Paris polyphylla. However, liver toxicity of these compounds has impeded their clinical application and the potential hepatotoxicity mechanisms remain to be elucidated. In

Increasing the Ascomycin Yield by Relieving the Inhibition of Acetyl/Propionyl-CoA Carboxylase by the Signal Transduction Protein GlnB

Frontiers in Microbiology, 2021
Ascomycin (FK520) is a multifunctional antibiotic produced by Streptomyces hygroscopicus var. ascomyceticus. In this study, we demonstrated that the inactivation of GlnB, a signal transduction protein belonging to the PII family, can increase the ...

Small protein mediates inhibition of ammonium transport in Methanosarcina mazei—an ancient mechanism?

Microbiology Spectrum, 2023
In the past decade, small open reading frames (sORFs) coding for proteins less than 70 amino acids (aa) in length have moved into the focus of science. sORFs and the corresponding small proteins have been recently identified in all three domains of life.

Uridylylation of the P_II protein in Rhizobium leguminosarum [PDF]

FEBS Letters, 1993
Permeabilization with cetyl trimethyl ammonium bromide was used to study the post‐translational modification of the PII protein in Rhizobium leguminosarum. Upon incubation with radioactive UTP a single band was obtained after SDS‐PAGE and autoradiography.
