The molecular structure of the fibrillar form of IAPP is subject of intense research, and to date, different models exist. We present results of solid-state NMR experiments on fibrils of recombinantly expressed and uniformly 13C, 15N-labeled human IAPP in the non-amidated, free acid form. Complete sequential resonance assignments and resulting constraints on secondary structure are shown. A single set of chemical shifts is found for most residues, which is indicative of a high degree of homogeneity. The core region comprises three to four β-sheets. We find that the central 23-FGAILS-28 segment, which is of critical importance for amyloid formation, is part of the core region and forms a β-strand in our sample preparation. The eight N-terminal amino acid residues of IAPP, forming a ring-like structure due to a disulfide bridge between residues C2 and C7, appear to be well defined but with an increased degree of flexibility. This study supports the elucidation of the structural basis of IAPP amyloid formation and highlights the extent of amyloid fibril polymorphism. 000821070 536__ $$0G:(DE-HGF)POF3-553$$a553 - Physical Basis of Diseases (POF3-553)$$cPOF3-553$$fPOF III$$x0 000821070 588__ $$aDataset connected to CrossRef 000821070 7001_ $$0P:(DE-Juel1)145165$$aGremer, Lothar$$b1$$ufzj 000821070 7001_ $$0P:(DE-HGF)0$$aMirecka, Ewa A.$$b2 000821070 7001_ $$0P:(DE-HGF)0$$aSchiefer, Stephanie$$b3 000821070 7001_ $$0P:(DE-Juel1)166306$$aHoyer, Wolfgang$$b4$$ufzj 000821070 7001_ $$0P:(DE-Juel1)132002$$aHeise, Henrike$$b5$$eCorresponding author$$ufzj 000821070 773__ $$0PERI:(DE-600)2267670-3$$a10.1371/journal.pone.0161243$$gVol. 11, no. 9, p. e0161243 -$$n9$$pe0161243$$tPLoS one$$v11$$x1932-6203$$y2016 000821070 8564_ $$uhttps://juser.fz-juelich.de/record/821070/files/Structural%20Characterization%20of%20Fibrils%20from%20Recombinant%20Human%20Islet%20Amyloid%20Polypeptide%20by%20Solid-State%20NMR%3A%20The%20Central%20FGAILS%20Segment%20Is%20Part%20of%20the%20%CE%B2-Sheet%20Core_2016.pdf$$yOpenAccess 000821070 8564_ $$uhttps://juser.fz-juelich.de/record/821070/files/Structural%20Characterization%20of%20Fibrils%20from%20Recombinant%20Human%20Islet%20Amyloid%20Polypeptide%20by%20Solid-State%20NMR%3A%20The%20Central%20FGAILS%20Segment%20Is%20Part%20of%20the%20%CE%B2-Sheet%20Core_2016.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000821070 8767_ $$92016-08-16$$d2016-08-23$$eAPC$$jZahlung erfolgt$$pPONE-D-16-11910$$zUSD 1495,- 000821070 909CO $$ooai:juser.fz-juelich.de:821070$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire$$pdnbdelivery 000821070 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)161487$$aForschungszentrum Jülich$$b0$$kFZJ 000821070 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)145165$$aForschungszentrum Jülich$$b1$$kFZJ 000821070 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)166306$$aForschungszentrum Jülich$$b4$$kFZJ 000821070 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)132002$$aForschungszentrum Jülich$$b5$$kFZJ 000821070 9131_ $$0G:(DE-HGF)POF3-553$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vPhysical Basis of Diseases$$x0 000821070 9141_ $$y2016 000821070 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000821070 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000821070 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000821070 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search 000821070 915__ $$0StatID:(DE-HGF)1040$$2StatID$$aDBCoverage$$bZoological Record 000821070 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bPLOS ONE : 2015 000821070 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000821070 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000821070 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000821070 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000821070 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000821070 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000821070 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC 000821070 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000821070 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000821070 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000821070 920__ $$lyes 000821070 9201_ $$0I:(DE-Juel1)ICS-6-20110106$$kICS-6$$lStrukturbiochemie $$x0 000821070 9801_ $$aFullTexts 000821070 980__ $$ajournal 000821070 980__ $$aVDB 000821070 980__ $$aUNRESTRICTED 000821070 980__ $$aI:(DE-Juel1)ICS-6-20110106 000821070 980__ $$aAPC 000821070 981__ $$aI:(DE-Juel1)IBI-7-20200312
