Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful technique capable of studying timescales of motion that range from those faster than molecular reorientation on the picosecond timescale to those that occur in real-time. Across this entire regime, NMR observables can report on the amplitude of atomic motion, and the kinetics of atomic motion can be ascertained with a wide variety of experimental techniques from real-time to milliseconds and several nanoseconds to picoseconds. Still a four orders of magnitude window between several nanoseconds and tens of microseconds has remained elusive. Here, we highlight new relaxation dispersion NMR techniques that serve to cover this \"hidden-time\" window up to hundreds of nanoseconds that achieve atomic resolution while studying the molecule under physiological conditions."],["dc.identifier.doi","10.1016/j.abb.2017.05.016"],["dc.identifier.pmid","28576576"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/11679"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.eissn","1096-0384"],["dc.title","Recent advances in measuring the kinetics of biomolecules by NMR relaxation dispersion spectroscopy"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

The Bacillus subtilis GlcT antitermination protein regulates the expression of the ptsG gene, encoding the glucose-specific enzyme II of the phosphotransferase system. In the absence of glucose, GlcT becomes inactivated by enzyme II-dependent phosphorylation at its PRD1, whereas the phosphotransferase HPr phosphorylates PRD2. However, here we demonstrate by NMR analysis and mass spectrometry that HPr also phosphorylates PRD1 in vitro but with low efficiency. Size exclusion chromatography revealed that non-phosphorylated PRD1 forms dimers that dissociate upon phosphorylation. The effect of HPr on PRD1 was also investigated in vivo. For this purpose, we used GlcT variants with altered domain arrangements or domain deletions. Our results demonstrate that HPr can target PRD1 when this domain is placed at the C terminus of the protein. In agreement with the in vitro data, HPr exerts a negative control on PRD1. This work provides the first insights into how specificity is achieved in a regulator that contains duplicated regulatory domains with distinct dimerization properties that are controlled by phosphorylation by different phosphate donors. Moreover, the results suggest that the domain arrangement of the PRD-containing antitermination proteins is under selective pressure to ensure the proper regulatory output, i.e. transcription antitermination of the target genes specifically in the presence of the corresponding sugar."],["dc.identifier.doi","10.1074/jbc.M112.388850"],["dc.identifier.gro","3142483"],["dc.identifier.isi","000307840700047"],["dc.identifier.pmid","22722928"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8785"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Amer Soc Biochemistry Molecular Biology Inc"],["dc.relation.issn","0021-9258"],["dc.title","Determinants of Interaction Specificity of the Bacillus subtilis GlcT Antitermination Protein FUNCTIONALITY AND PHOSPHORYLATION SPECIFICITY DEPEND ON THE ARRANGEMENT OF THE REGULATORY DOMAINS"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]

Importantly, Ca²⁺–CaM binds a conserved region in the priming proteins Munc13‐1 and ubMunc13‐2 and thus regulates synaptic neurotransmitter release in neurons in response to residual Ca2+ signals. We solved the structure of Ca²⁺₄–CaM in complex with the CaM‐binding domain of Munc13‐1, which features a novel 1‐5‐8‐26 CaM‐binding motif with two separated mobile structural modules, each involving a CaM domain. Photoaffinity labelling data reveal the same modular architecture in the complex with the ubMunc13‐2 isoform. The N‐module can be dissociated with EGTA to form the half‐loaded Munc13/Ca²⁺₂–CaM complex. The Ca²⁺ regulation of these Munc13 isoforms can therefore be explained by the modular nature of the Munc13/Ca²⁺–CaM interactions, where the C‐module provides a high‐affinity interaction activated at nanomolar [Ca²⁺]i, whereas the N‐module acts as a sensor at micromolar [Ca²⁺]i. This Ca²⁺/CaM‐binding mode of Munc13 likely constitutes a key molecular correlate of the characteristic Ca²⁺‐dependent modulation of short‐term synaptic plasticity."],["dc.identifier.doi","10.1038/emboj.2009.373"],["dc.identifier.gro","3142967"],["dc.identifier.isi","000274233400015"],["dc.identifier.pmid","20010694"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/429"],["dc.notes.intern","WoS Import 2017-03-10 / Funder: Max-Planck Society; Fonds der Chemischen Industrie"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","0261-4189"],["dc.title","Modular architecture of Munc13/calmodulin complexes: dual regulation by Ca²⁺ and possible function in short-term synaptic plasticity"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]

Relaxation dispersion (RD) NMR experiments sensitively probe microsecond to millisecond motions. We conducted an in-depth RD analysis of the backbone and side chain methyl groups of ubquitin. This survey showed a large number of atoms (>30) with microsecond fluctuations. These atoms are distributed throughout the structure. 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”. We present a single collective mode of motion that yields a reaction coordinate corresponding to the relaxation dispersion data. The resulting model indicates that a localized conformational switch distant from the binding interface propagates changes throughout the structure.

Here, we analyze the temperature dependence of internal methyl group dynamics derived from the cross-correlated relaxation between dipolar couplings of two CH bonds within ubiquitin. Spanning a temperature range from 275 to 308 K, internal methyl group dynamics tend to increase with increasing temperature, which translates to a general increase in local conformational entropy. With this data measured over multiple temperatures, the thermal coefficient of the methyl group order parameter, the characteristic thermal coefficient, and the local heat capacity were obtained.
