ACTIVATED RESPONSE REGULATOR PLED IN COMPLEX WITH C-DIGMP AND GTP- ALPHA-SACTIVATED RESPONSE REGULATOR PLED IN COMPLEX WITH C-DIGMP AND GTP- ALPHA-S
Structural highlights
FunctionPLED_CAUVN Response regulator that is part of a signal transduction pathway controlling cell differentiation in the swarmer-to-stalked cell transition.[1] Catalyzes the condensation of two GTP molecules to the cyclic dinucleotide di-GMP (c-di-GMP), which acts as a secondary messenger.[2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedCyclic di-guanosine monophosphate (c-di-GMP) is a ubiquitous bacterial second messenger involved in the regulation of cell surface-associated traits and persistence. We have determined the crystal structure of PleD from Caulobacter crescentus, a response regulator with a diguanylate cyclase (DGC) domain, in its activated form. The BeF(3)(-) modification of its receiver domain causes rearrangement with respect to an adaptor domain, which, in turn, promotes dimer formation, allowing for the efficient encounter of two symmetric catalytic domains. The substrate analog GTPalphaS and two putative cations are bound to the active sites in a manner similar to adenylate cyclases, suggesting an analogous two-metal catalytic mechanism. An allosteric c-di-GMP-binding mode that crosslinks DGC and an adaptor domain had been identified before. Here, a second mode is observed that crosslinks the DGC domains within a PleD dimer. Both modes cause noncompetitive product inhibition by domain immobilization.
