In this work, we report that recombinant 100% N\u2010terminal acetylated \u03b1\u2010synuclein purified under mild physiological conditions presents as a primarily monomeric protein, and that the N\u2010terminal acetyl group affects the transient secondary structure and fibril assembly rates of the protein. Residue\u2010specific NMR chemical shift analysis indicates substantial increase in transient helical propensity in the first 9 N\u2010terminal residues, as well as smaller long\u2010range changes in residues 28\u201331, 43\u201346, and 50\u201366: regions in which the three familial mutations currently known to be causative of early onset disease are found. In addition, we show that the N\u2010terminal acetylated protein forms fibrils that are morphologically similar to those formed from nonacetylated \u03b1\u2010synuclein, but that their growth rates are slower. Our results highlight that N\u2010terminal acetylation does not form significant numbers of dimers, tetramers, or higher molecular weight species, but does alter the conformational distributions of monomeric \u03b1\u2010synuclein species in regions known to be important in metal binding, in association with membranes, and in regions known to affect fibril formation rates.<\/jats:p>","DOI":"10.1002\/pro.2088","type":"journal-article","created":{"date-parts":[[2012,5,9]],"date-time":"2012-05-09T15:16:33Z","timestamp":1336576593000},"page":"911-917","source":"Crossref","is-referenced-by-count":194,"title":["N\u2010terminal
