The inhibition of growth was correlated with the accumulation of the substrate, 24\u2010methylene\u201024,25\u2010dihydrolanosterol (eburicol), and depletion of ergosterol. Mutants overcoming the effect of azole antifungal treatment exhibited a unique phenotype with leaky CYP51A1 activity which was resistant to inhibition. The results demonstrate that alterations at the level of inhibitor binding to the target site can produce azole resistance. Similar changes may account for fungal azole resistance phenomena in agriculture, and also in medicine where resistance has become a problem in immuno\u2010compromised patients suffering from AIDS.<\/jats:p>","DOI":"10.1016\/0014-5793(95)01102-k","type":"journal-article","created":{"date-parts":[[2003,5,13]],"date-time":"2003-05-13T01:07:27Z","timestamp":1052788047000},"page":"174-178","source":"Crossref","is-referenced-by-count":51,"title":["Altered P450 activity associated with direct selection for fungal azole resistance"],"prefix":"10.1002","volume":"374","author":[{"given":"T.","family":"Joseph-Horne","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Hollomon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.S.T.","family":"Loeffler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.L.","family":"Kelly","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2000,3,9]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1089\/dna.1993.12.1"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(17)43458-2"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9258(18)51495-2"},{"key":"e_1_2_1_5_1","first-page":"1035","volume":"21","author":"Kelly S.L.","year":"1993","journal-title":"Biochem.
