Information on how the signal is transmitted across the membrane by HKs is still scarce. Combining both liquid- and solid-state NMR, we demonstrate that structural rearrangements in the extracytoplasmic, citrate-sensing Per-Arnt-Sim (PAS) domain of HK CitA are identical for the isolated domain in solution and in a longer construct containing the membrane-embedded HK and lacking only the kinase core. We show that upon citrate binding, the PAS domain contracts, resulting in a shortening of the C-terminal β-strand. We demonstrate that this contraction of the PAS domain, which is well characterized for the isolated domain, is the signal transmitted to the transmembrane (TM) helices in a CitA construct in liposomes. Putting the extracytoplasmic PAS domain into context of the membrane-embedded CitA construct slows down citrate-binding kinetics by at least a factor of 60, confirming that TM helix motions are linked to the citrate-binding event. Our results are confirmation of a hallmark of the HK signal transduction mechanism with atomic resolution on a full-length construct lacking only the kinase core domain."],["dc.identifier.doi","10.1073/pnas.1620286114"],["dc.identifier.pmid","28265100"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/11680"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.eissn","1091-6490"],["dc.title","Sensory domain contraction in histidine kinase CitA triggers transmembrane signaling in the membrane-bound sensor"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

In this work, we employed a spectroelectrochemical approach to probe the voltage-induced molecular structure changes of human VDAC1 (hVDAC1) embedded in a tethered bilayer lipid membrane on a nanostructured Au electrode. The model membrane consisted of a mixed self-assembled monolayer of 6-mercaptohexanol and (cholesterylpolyethylenoxy) thiol, followed by the deposition of 1-palmitoyl-2- oleoyl-sn-glycero-3-phosphocholine vesicles including hVDAC1. The stepwise assembly of the model membrane and the incorporation of hVDAC1 were monitored by surface enhanced infrared absorption and electrochemical impedance spectroscopy. Difference spectra allowed for identifying the spectral changes which may be associated with the transition from the open to the \"closed' states by shifting the potential above or below the transmembrane potential determined to be ca. 0.0 V vs. the open circuit potential. These spectral changes were interpreted on the basis of the orientation-and distancedependent IR enhancement and indicate alterations of the inclination angle of the beta-strands as crucial molecular events, reflecting an expansion or contraction of the beta-barrel pore.

We present a theoretical and experimental framework based on straight-forward nuclear magnetic resonance relaxation dispersion measurements to investigate protein binding mechanisms on sub-millisecond timescales, which are beyond the reach of standard rapid-mixing experiments. This framework predicts that conformational selection prevails on ubiquitin’s paradigmatic interaction with an SH3 (Src-homology 3) domain. By contrast, the SH3 domain recognizes ubiquitin in a two-state binding process. Subsequent molecular dynamics simulations and Markov state modeling reveal that the ubiquitin conformation selected for binding exhibits a characteristically extended C-terminus. Our framework is robust and expandable for implementation in other binding scenarios with the potential to show that conformational selection might be the design principle of the hubs in protein interaction networks."],["dc.identifier.doi","10.1038/s41467-022-31374-5"],["dc.identifier.pii","31374"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/113597"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-597"],["dc.relation.eissn","2041-1723"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","A litmus test for classifying recognition mechanisms of transiently binding proteins"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

The CREB-binding protein (p300/CBP) and the nuclear coactivator I (NCoA-1), a member of the p160/steroid receptor coactivator family, bind independently to specific regions of the STAT6 transactivation domain and act as coactivators. The interaction between STAT6 and NCoA-1 is mediated by an LXXLL motif in the transactivation domain of STAT6. To define the mechanism of coactivator recognition, we determined the crystal structure of the NCoA-1 PAS-B domain in complex with the STAT6 LXXLL motif. The amphipathic, alpha-helical STAT6 LXXLL motif binds mostly through specific hydrophobic interactions to NCoA-1. A single amino acid of the NCoA-1 PAS-B domain establishes hydrophilic interactions with the STAT6 peptide. STAT6 interacts only with the PAS-B domain of NCoA-1 but not with the homologous regions of NCoA-2 and NCoA-3. The residues involved in binding the STAT6 peptide are strongly conserved between the different NCoA family members. Therefore surface complementarity between the hydrophobic faces of the STAT6 fragment and of the NCoA-1 PAS-B domain almost exclusively defines the binding specificity between the two proteins.

Strikingly, nearly all show the same exchange rate, which suggests that ubiquitin undergoes collective motion involving both the backbone and side chains. Furthermore, comparison of different methyl nuclei indicates that the nature of the side chain fluctuations is almost entirely due to changes in rotamer populations. Thus, collective microsecond backbone motion is coupled to redistribution of side chain rotamer populations through a mechanism we term “population shuffling”.
