The PII-NAGK-PipX-NtcA Regulatory Axis of Cyanobacteria: A Tale of Changing Partners, Allosteric Effectors and Non-covalent Interactions [PDF]

Frontiers in Molecular Biosciences, 2018
PII, a homotrimeric very ancient and highly widespread (bacteria, archaea, plants) key sensor-transducer protein, conveys signals of abundance or poorness of carbon, energy and usable nitrogen, converting these signals into changes in the activities of ...

Uridylylation of the PII protein fromHerbaspirillum seropedicae

Canadian Journal of Microbiology, 2001
The PII protein is apparently involved in the control of NifA activity in Herbaspirillum seropedicae. To evaluate the probable role of PII in signal transduction, uridylylation assays were conducted with purified H. seropedicae PII and Escherichia coli GlnD, or a cell-free extract of H. seropedicae as sources of uridylylating activity.

Adenylylation of mycobacterial Glnk (PII) protein is induced by nitrogen limitation.

Tuberculosis (Edinb), 2013
PII proteins are pivotal regulators of nitrogen metabolism in most prokaryotes, controlling the activities of many targets, including nitrogen assimilation enzymes, two component regulatory systems and ammonium transport proteins. Escherichia coli contains two PII-like proteins, PII (product of glnB) and GlnK, both of which are uridylylated under ...

Expression and molecular characterization of the Mycobacterium tuberculosis PII protein

The Journal of Biochemistry, 2010
The signal transduction protein PII plays an important role in cellular nitrogen assimilation and regulation. The molecular characteristics of the Mycobacterium tuberculosis PII (Mtb PII) were investigated using biophysical experiments. The Mtb PII coding ORF Rv2919c was cloned and expressed in Escherichia coli.

Interaction of the nitrogen regulatory protein GlnB (PII) with biotin carboxyl carrier protein (BCCP) controls Acetyl-CoA levels in the cyanobacterium Synechocystis sp. PCC 6803 [PDF]

Frontiers in Microbiology, 2016
The family of PII signal transduction proteins (members GlnB, GlnK, NifI) plays key roles in various cellular processes related to nitrogen metabolism at different functional levels.

PII protein is essential for transcriptional regulation of anf gene cluster for iron-only nitrogenase in Rhodopseudomonas palustris [PDF]

Applied and Environmental Microbiology
In addition to catalyzing the biological nitrogen fixation, iron-only (Fe-only) nitrogenase is also able to reduce carbon dioxide (CO2) to formate (HCOO−) and methane (CH4).

Formation of NifA-PII complex represses ammonium-sensitive nitrogen fixation in diazotrophic proteobacteria lacking NifL

Cell Reports
Summary: Biological nitrogen fixation catalyzed by nitrogenase contributes greatly to the global nitrogen cycle. Nitrogenase expression is subject to regulation in response to nitrogen availability.
