Techniques to measure accurately long distances in many classes of heme proteins using DEER are currently strongly limited by sensitivity. In this paper we demonstrate sensitivity gains of more than 30 times compared with previous lower frequency (X-band) DEER measurements on both human neuroglobin and sperm whale myoglobin. This is achieved by taking advantage of recent instrumental advances, employing wideband excitation techniques based on composite pulses and exploiting more favorable relaxation properties of low-spin Fe(III) in high magnetic fields. This gain in sensitivity potentially allows the DEER technique to be routinely used as a sensitive probe of structure and conformation in the large number of heme and many other metalloproteins.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6b00456","type":"journal-article","created":{"date-parts":[[2016,4,1]],"date-time":"2016-04-01T13:34:23Z","timestamp":1459517663000},"page":"1411-1415","source":"Crossref","is-referenced-by-count":42,"title":["DEER Sensitivity between Iron Centers and Nitroxides\nin Heme-Containing Proteins Improves Dramatically Using Broadband,\nHigh-Field EPR"],"prefix":"10.1021","volume":"7","author":[{"given":"Claire L.","family":"Motion","sequence":"first","affiliation":[{"name":"University of St Andrews , , North Haugh , , , ,","place":["St. Andrews, Fife, United Kingdom, KY16 9SS"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janet E.","family":"Lovett","sequence":"additional","affiliation":[{"name":"University of St Andrews , , North Haugh , , , ,","place":["St. Andrews, Fife, United Kingdom, KY16 9SS"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stacey","family":"Bell","sequence":"additional","affiliation":[{"name":"University of St Andrews , , North Haugh , , , ,","place":["St. Andrews, Fife, United Kingdom, KY16 9SS"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott L.","family":"Cassidy","sequence":"additional","affiliation":[{"name":"University of St Andrews , , North Haugh , , , ,","place":["St. Andrews, Fife, United Kingdom, KY16 9SS"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.
