This mutation of mCherry for rsCherryRev has caused ultrafast relaxation with lifetimes of \u223c0.3 ps and \u223c3 ps much faster than the lifetime of mCherry (\u223c0.5 ns). The ultrashort lifetimes of rsCherryRev are considered to reflect the initial structural change of the chromophore during photoisomerization. The ultrashort duration of 10 fs laser pulse also visualizes that the C\u2550C stretching mode intensity increases at \u223c0.7 ps delay, reflecting the timing of photoisomerization in rsCherryRev.<\/jats:p>","DOI":"10.1021\/acs.jpcb.6c02790","type":"journal-article","created":{"date-parts":[[2026,8,13]],"date-time":"2026-08-13T14:01:59Z","timestamp":1786629719000},"page":"8735-8743","source":"Crossref","is-referenced-by-count":0,"title":["Ultrafast Dynamics\nof rsCherryRev in Comparison with\nmCherry Reflecting Its Reversive Switchability"],"prefix":"10.1021","volume":"130","author":[{"given":"Yu-Sheng","family":"Tsai","sequence":"first","affiliation":[{"name":"National Yang Ming Chiao Tung University , , ,","place":["Hsinchu, Taiwan, 300"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7081-2173","authenticated-orcid":true,"given":"Sheng-Ting","family":"Hung","sequence":"additional","affiliation":[{"name":"National Sun Yat-Sen University , , ,","place":["Kaohsiung, Taiwan, 80424"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chuang-Yu","family":"Lin","sequence":"additional","affiliation":[{"name":"Kaohsiung Medical University , , ,","place":["Kaohsiung, Taiwan, 80708"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ai","family":"Hsu","sequence":"additional","affiliation":[{"name":"Kaohsiung Medical University , , ,","place":["Kaohsiung, Taiwan, 80708"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo-Ting","family":"Chen","sequence":"additional","affiliation":[{"name":"National Sun Yat-Sen University , , ,","place":["Kaohsiung, Taiwan, 80424"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takayoshi","family":"Kobayashi","sequence":"additional","affiliation":[{"name":"National Yang Ming Chiao Tung University , , ,","place":["Hsinchu, Taiwan, 300"]},{"name":"Kanagawa University , , , ,","place":["Yokohama, Kanagawa, Japan, 221-8686"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9308-4298","authenticated-orcid":true,"given":"Atsushi","family":"Yabushita","sequence":"additional","affiliation":[{"name":"National Yang Ming Chiao Tung University , , ,","place":["Hsinchu, Taiwan, 300"]},{"name":"Kanagawa University , , , ,","place":["Yokohama, Kanagawa, Japan, 221-8686"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,13]]},"reference":[{"key":"2026090114351862400_cit1","doi-asserted-by":"publisher","first-page":"223","DOI":"10.1002\/JCP.1030590302","article-title":"Extraction Purification and Properties\nof Aequorin, a Bioluminescent Protein from the Luminous Hydromedusan,\nAequorea","volume":"59","author":"Shimomura","year":"1962","journal-title":"J.
