This work provides insights into the elastic properties of elastin and its peculiar inverse temperature transition (ITT). These features are dependent on hydration of elastin and are driven by a similar mechanism of hydrophobic collapse to an entropically favorable state. Using neutron scattering, we quantify the changes in the geometry of molecular motions above and below the transition temperature, showing a reduction in the displacement of water-induced motions upon hydrophobic collapse at the ITT. We also measured the collective vibrations of elastin gels as a function of elongation, revealing no changes in the spectral features associated with local rigidity and secondary structure, in agreement with the entropic origin of elasticity. 000255669 536__ $$0G:(DE-HGF)POF3-551$$a551 - Functional Macromolecules and Complexes (POF3-551)$$cPOF3-551$$fPOF III$$x0 000255669 536__ $$0G:(DE-HGF)POF3-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)$$cPOF3-623$$fPOF III$$x1 000255669 536__ $$0G:(DE-HGF)POF3-6215$$a6215 - Soft Matter, Health and Life Sciences (POF3-621)$$cPOF3-621$$fPOF III$$x2 000255669 588__ $$aDataset connected to CrossRef 000255669 7001_ $$0P:(DE-HGF)0$$aEhlers, Georg$$b1 000255669 7001_ $$0P:(DE-Juel1)143752$$aJalarvo, Niina$$b2$$ufzj 000255669 7001_ $$0P:(DE-HGF)0$$aKatsaras, John$$b3 000255669 7001_ $$0P:(DE-HGF)0$$aNickels, Jonathan D.$$b4 000255669 773__ $$0PERI:(DE-600)2522838-9$$a10.1021/acs.jpclett.5b01890$$gp. 150922143252007 -$$p4018–4025$$tThe @journal of physical chemistry letters$$v6$$x1948-7185$$y2015 000255669 8564_ $$uhttps://juser.fz-juelich.de/record/255669/files/acs%252Ejpclett%252E5b01890.pdf$$yRestricted 000255669 8564_ $$uhttps://juser.fz-juelich.de/record/255669/files/acs%252Ejpclett%252E5b01890.gif?subformat=icon$$xicon$$yRestricted 000255669 8564_ $$uhttps://juser.fz-juelich.de/record/255669/files/acs%252Ejpclett%252E5b01890.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000255669 8564_ $$uhttps://juser.fz-juelich.de/record/255669/files/acs%252Ejpclett%252E5b01890.jpg?subformat=icon-180$$xicon-180$$yRestricted 000255669 8564_ $$uhttps://juser.fz-juelich.de/record/255669/files/acs%252Ejpclett%252E5b01890.jpg?subformat=icon-640$$xicon-640$$yRestricted 000255669 8564_ $$uhttps://juser.fz-juelich.de/record/255669/files/acs%252Ejpclett%252E5b01890.pdf?subformat=pdfa$$xpdfa$$yRestricted 000255669 909CO $$ooai:juser.fz-juelich.de:255669$$pVDB 000255669 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ PHYS CHEM LETT : 2014 000255669 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000255669 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000255669 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000255669 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000255669 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000255669 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000255669 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000255669 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000255669 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bJ PHYS CHEM LETT : 2014 000255669 9141_ $$y2015 000255669 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)143752$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000255669 9131_ $$0G:(DE-HGF)POF3-551$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vFunctional Macromolecules and Complexes$$x0 000255669 9131_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G4$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Neutrons for Research on Condensed Matter$$x1 000255669 9131_ $$0G:(DE-HGF)POF3-621$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6215$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vIn-house research on the structure, dynamics and function of matter$$x2 000255669 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kNeutronenstreuung ; JCNS-1$$lNeutronenstreuung$$x0 000255669 9201_ $$0I:(DE-Juel1)ICS-1-20110106$$kICS-1$$lNeutronenstreuung$$x1 000255669 9201_ $$0I:(DE-Juel1)JCNS-SNS-20110128$$kJCNS-SNS$$lJCNS-SNS$$x2 000255669 980__ $$ajournal 000255669 980__ $$aVDB 000255669 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000255669 980__ $$aI:(DE-Juel1)ICS-1-20110106 000255669 980__ $$aI:(DE-Juel1)JCNS-SNS-20110128 000255669 980__ $$aUNRESTRICTED 000255669 981__ $$aI:(DE-Juel1)IBI-8-20200312 000255669 981__ $$aI:(DE-Juel1)JCNS-1-20110106 000255669 981__ $$aI:(DE-Juel1)ICS-1-20110106 000255669 981__ $$aI:(DE-Juel1)JCNS-SNS-20110128
