Beschreibung:
<jats:p> The PII carbon/nitrogen sensing protein was discovered in Escherichia coli (Migula 1895) Castellani and Chalmers 1919, over 40 years ago. Orthologues have been discovered in three kingdoms of life making it one of the most ancient and conserved signaling proteins known. Recent advances in the field have established its primary binding partner in plants as N-acetyl glutamate kinase and the crystal structure has revealed features unique to plants that likely contribute to its function in vivo. Here, we review the properties, function, and novel structural features of this chloroplast-localized metabolic sensor of higher plants. </jats:p>
