Domain III (ED3) of the viral envelope protein contains the two dominant putative epitopes and part of the heparin sulfate receptor binding region that drives the dengue virus (DENV)\u2019s fusion with the host cell. Here, we used high-hydrostatic-pressure nuclear magnetic resonance (HHP-NMR) to obtain residue-specific information on the folding process of domain III from serotype 4 dengue virus (DEN4-ED3), which adopts the classical three-dimensional (3D) \u00df-sandwich structure known as the Ig-like fold. Interestingly, the folding pathway of DEN4-ED3 shares similarities with that of the Titin I27 module, which also adopts an Ig-like fold, but is functionally unrelated to ED3. For both proteins, the unfolding process starts by the disruption of the N- and C-terminal strands on one edge of the \u00df-sandwich, yielding a folding intermediate stable over a substantial pressure range (from 600 to 1000 bar). In contrast to this similarity, pressure-jump kinetics indicated that the folding transition state is considerably more hydrated in DEN4-ED3 than in Titin I27.<\/jats:p>","DOI":"10.3390\/biom9080309","type":"journal-article","created":{"date-parts":[[2019,7,26]],"date-time":"2019-07-26T11:55:22Z","timestamp":1564142122000},"page":"309","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Folding of the Ig-Like Domain of the Dengue Virus Envelope Protein Analyzed by High-Hydrostatic-Pressure NMR at a Residue-Level Resolution"],"prefix":"10.3390","volume":"9","author":[{"given":"Tomonori","family":"Saotome","sequence":"first","affiliation":[{"name":"Department of Biotechnology and Life Science, Tokyo University of Agriculture and Technology, 2-24-16, Nakamachi, Koganei, Tokyo 184-8588, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8312-3353","authenticated-orcid":false,"given":"Maxime","family":"Doret","sequence":"additional","affiliation":[{"name":"Centre de Biochimie Structurale, CNRS UMR 5048, University of Montpellier-INSERM U 1054, 29 Rue de Navacelles, 34090 Montpellier, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manjiri","family":"Kulkarni","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Life Science, Tokyo University of Agriculture and Technology, 2-24-16, Nakamachi, Koganei, Tokyo 184-8588, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yin-Shan","family":"Yang","sequence":"additional","affiliation":[{"name":"Centre de Biochimie Structurale, CNRS UMR 5048, University of Montpellier-INSERM U 1054, 29 Rue de Navacelles, 34090 Montpellier, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Barthe","sequence":"additional","affiliation":[{"name":"Centre de Biochimie Structurale, CNRS UMR 5048, University of Montpellier-INSERM U 1054, 29 Rue de Navacelles, 34090 Montpellier, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yutaka","family":"Kuroda","sequence":"additional","affiliation":[{"name":"Department of Biotechnology and Life Science, Tokyo University of Agriculture and Technology, 2-24-16, Nakamachi, Koganei, Tokyo 184-8588, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4082-3293","authenticated-orcid":false,"given":"Christian","family":"Roumestand","sequence":"additional","affiliation":[{"name":"Centre de Biochimie Structurale, CNRS UMR 5048, University of Montpellier-INSERM U 1054, 29 Rue de Navacelles, 34090 Montpellier, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2395","DOI":"10.1073\/pnas.91.7.2395","article-title":"Dengue: the risk to developed and developing countries","volume":"91","author":"Monath","year":"1994","journal-title":"Proc.
