Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Method: X-ray diffraction, Resolution 2.1Å Ligands: SO4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT, TOPSAN Function DARB_BACSU Involved in the c-di-AMP-dependent regulation of the bacterial stringent response (PubMed:33619274, PubMed:35130724). Modulates the activities of at least two enzymes under conditions of potassium limitation (PubMed:33619274, PubMed:35130724). Apo-DarB regulates the activity of the GTP pyrophosphokinase RelA by interacting directly with RelA, leading to stimulation of (p)ppGpp synthesis and induction of the stringent response (PubMed:33619274). Apo-DarB also regulates pyruvate carboxylase (PYC) at two levels: directly at the protein level by binding to the enzyme and stimulating the synthesis of oxaloacetate and indirectly, by interaction with RelA, which leads to activation of the stringent response and to the increased expression of the pycA gene (PubMed:35130724). Stimulation of these enzymes by DarB is prevented in the presence of cyclic di-AMP (c-di-AMP) (PubMed:33619274, PubMed:35130724). Evolutionary Conservation Check, as determined by ConSurfDB.
