Under the usual low resolution conditions employed in COSY, the intensities of cross peaks depend on the magnitudes of coupling constants. There are five vicinal coupling constants in a deoxyribose ring which are sensitive to the sugar geometry. The presence, absence and rough comparison of relative intensities of COSY cross peaks arising from such coupling constants enable one to fix the sugar conformation to a fair degree of precision. The methodology has been applied to d\u2010GAATTCGAATTC. It is observed that ten out of the twelve nucleotide units in this sequence exhibit a rare Ol\u2032\u2010endo geometry. The <jats:italic>Eco<\/jats:italic>RI cleavage sites (between G and A) in the dodecanucleotide show an interesting variation in the conformation with the two sugars attached to the Gs acquiring a geometry between C2\u2032\u2010endo and C4\u2032\u2010endo.<\/jats:p>","DOI":"10.1016\/0014-5793(86)80868-7","type":"journal-article","created":{"date-parts":[[2002,7,25]],"date-time":"2002-07-25T07:57:40Z","timestamp":1027583860000},"page":"71-76","source":"Crossref","is-referenced-by-count":35,"title":["Solution structure of d\u2010GAATTCGAATTC by 2D NMR"],"prefix":"10.1002","volume":"205","author":[{"given":"R.V.","family":"Hosur","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Ravikumar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.V.R.","family":"Chary","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anu","family":"Sheth","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Girjesh","family":"Govil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tan","family":"Zu-Kun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.Todd","family":"Miles","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2001,10,29]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-68097-7"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4612-5190-3"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0079-6565(78)80006-5"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4613-9397-9"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja00778a043"},{"key":"e_1_2_1_7_1","first-page":"243","volume-title":"Magnetic Resonance in Biology and Medicine","author":"Hosur R.V.","year":"1985"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1021\/bi00347a030"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0014-5793(85)80516-0"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0079-6565(85)80004-2"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1021\/bi00300a001"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/0009-2614(85)80135-4"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-2364(84)90040-4"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-2364(85)90022-8"},{"key":"e_1_2_1_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-2836(83)90096-7"}],"container-title":["FEBS Letters"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1016%2F0014-5793%2886%2980868-7","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1016%2F0014-5793(86)80868-7","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/febs.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/0014-5793%2886%2980868-7","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,16]],"date-time":"2023-09-16T23:03:23Z","timestamp":1694905403000},"score":1,"resource":{"primary":{"URL":"https:\/\/febs.onlinelibrary.wiley.com\/doi\/10.1016\/0014-5793%2886%2980868-7"}},"subtitle":["A new approach to determination of sugar geometries in DNA segments"],"short-title":[],"issued":{"date-parts":[[1986,9]]},"references-count":14,"journal-issue":{"issue":"1","published-print":{"date-parts":[[1986,9]]}},"alternative-id":["10.1016\/0014-5793(86)80868-7"],"URL":"https:\/\/doi.org\/10.1016\/0014-5793(86)80868-7","archive":["Portico"],"relation":{},"ISSN":["0014-5793","1873-3468"],"issn-type":[{"value":"0014-5793","type":"print"},{"value":"1873-3468","type":"electronic"}],"subject":[],"published":{"date-parts":[[1986,9]]}}}
