The ubiquitous dipolar shifts for assigned residues, together with crystal coordinates of some appropriate structural homolog, allow determination of the orientation and anisotropies of the paramagnetic dipolar tensor. The orientation of \u03c7 uniquely defines the orientation of the Fe\u2010CN unit, which is tilted variably and sensitively monitors distal steric and H\u2010bond interactions. The mapped dipolar field, in turn, can be used to determine the orientation of mutated residues. Case studies involving unusual genetic variants and point mutants of myoglobins, human hemoglobins, horseradish peroxidase and its substrate complex of heme oxygenase are presented as examples.<\/jats:p>","DOI":"10.1080\/15216540701194121","type":"journal-article","created":{"date-parts":[[2007,8,14]],"date-time":"2007-08-14T04:12:33Z","timestamp":1187064753000},"page":"513-527","source":"Crossref","is-referenced-by-count":6,"title":["Application of the paramagnetic dipole field for solution NMR active site structure determination in low\u2010spin, cyanide\u2010inhibited ferric hemoproteins"],"prefix":"10.1002","volume":"59","author":[{"given":"Gerd N.","family":"La Mar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,1,3]]},"container-title":["IUBMB Life"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1080%2F15216540701194121","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/iubmb.onlinelibrary.wiley.com\/doi\/pdf\/10.1080\/15216540701194121","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T11:02:02Z","timestamp":1693479722000},"score":1,"resource":{"primary":{"URL":"https:\/\/iubmb.onlinelibrary.wiley.com\/doi\/10.1080\/15216540701194121"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,1]]},"references-count":0,"journal-issue":{"issue":"8-9","published-print":{"date-parts":[[2007,1]]}},"alternative-id":["10.1080\/15216540701194121"],"URL":"https:\/\/doi.org\/10.1080\/15216540701194121","archive":["Portico"],"relation":{},"ISSN":["1521-6543","1521-6551"],"issn-type":[{"value":"1521-6543","type":"print"},{"value":"1521-6551","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,1]]}}}
