In cyanobacteria, under conditions of low 2-oxoglutarate, PII forms complexes with the enzyme N-acetyl glutamate kinase, increasing arginine biosynthesis, and with PII-interacting protein X (Pip X), making Pip X unavailable for binding and co-activation of the nitrogen regulator Ntc A. doi: 10.1073/pnas.072587199 Pub Med Abstract | Cross Ref Full Text | Google Scholar Tirode, F., Malaguti, C., Romero, F., Attar, R., Camonis, J., and Egly, J.

Both the PII-Pip X complex structure and in vivo functional data suggested that this complex, as such, could have regulatory functions in addition to Pip X sequestration.

To show the position of mutated residues in relation to the Pip X molecule, PII residues are marked in one of two adjacent PII subunits. Fast, scalable generation of high-quality protein multiple sequence alignments using Clustal Omega.

The 7 residues insertion in the T-loop mutant is schematized with a dashed pink line. The N-terminal DNA binding winged helix-turn-helix (HTH) domains were modeled ( from the corresponding domains of the structure of DNA-bound Yvo A (PDB file 4WWC; Fillenberg et al., 2015). doi: 10.1101/gad.254714.114 Pub Med Abstract | Cross Ref Full Text | Google Scholar Sievers, F., Wilm, A., Dineen, D., Gibson, T.

The residues mutated here are mapped in one Pip X subunit (green spheres) having an “extended” C-terminal helix conformation and in PII (blue spheres) and are labeled.

Novel interactions mediated by PII and Pip X in cyanobacteria may provide a rationale for non-understood observations, including the need of PII for viability of S.

elongatus at relatively low carbon to nitrogen rations (Chang et al., 2013) and the involvement of Pip X in transcriptional regulation of cells grown in the presence of ammonium or nitrate (Espinosa et al., 2014).

Attempts to inactive plm A confirmed that this gene is essential in S. In silico studies showed that Plm A is universally and exclusively found in cyanobacteria.

Based on interaction data, on the relative amounts of the proteins involved in PII-Pip X-Plm A complexes, determined in western assays, and on the restrictions imposed by the symmetries of trimeric PII and dimeric Plm A molecules, a structural and regulatory model for Plm A function is discussed in the context of the cyanobacterial nitrogen interaction network.

Under nitrogen limitation, 2-OG stimulates Ntc A binding to target sites (Vázquez-Bermúdez et al., 2002), activating transcription (Tanigawa et al., 2002) and favoring complex formation between Ntc A and Pip X (Espinosa et al., 2006) (Figure 1A).
