Due to their ototoxic and nephrotoxic side effects, they are typically only used against Gram negative bacteria which have become resistant to other therapeutics. One family of aminoglycosides includes such compounds as butirosin, ribostamycin, neomycin, and kanamycin, amongst others. The common theme in these antibiotics is that they are constructed around a chemically stable aminocyclitol unit referred to as 2\u2010deoxystreptamine (2\u2010DOS). Four enzymes are required for the<jats:italic>in vivo<\/jats:italic>production of 2\u2010DOS. Here, we report the structure of RbmB from<jats:italic>Streptomyces ribosidificus<\/jats:italic>, which is a pyridoxal 5\u2032\u2010phosphate dependent enzyme that catalyzes two of the required steps in 2\u2010DOS formation by functioning on distinct substrates. For this analysis, the structure of the external aldimine form of RbmB with 2\u2010DOS was determined to 2.1 \u00c5 resolution. In addition, the structure of a similar enzyme, BtrR from<jats:italic>Bacillus circulans<\/jats:italic>, was also determined to 2.1 \u00c5 resolution in the same external aldimine form. These two structures represent the first detailed molecular descriptions of the active sites for those aminotransferases involved in 2\u2010DOS production. Given the fact that the 2\u2010DOS unit is widespread amongst aminoglycoside antibiotics, the data presented herein provide new molecular insight into the biosynthesis of these sugar\u2010based drugs.<\/jats:p>","DOI":"10.1002\/pro.3221","type":"journal-article","created":{"date-parts":[[2017,7,7]],"date-time":"2017-07-07T12:45:35Z","timestamp":1499431535000},"page":"1886-1892","source":"Crossref","is-referenced-by-count":9,"title":["The structure of RbmB from<i>Streptomyces ribosidificus<\/i>, an aminotransferase involved in the biosynthesis of ribostamycin"],"prefix":"10.1002","volume":"26","author":[{"given":"Trevor R.","family":"Zachman\u2010Brockmeyer","sequence":"first","affiliation":[{"name":"Department of Biochemistry University of Wisconsin Madison Wisconsin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James B.","family":"Thoden","sequence":"additional","affiliation":[{"name":"Department of Biochemistry University of Wisconsin Madison Wisconsin"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hazel M.","family":"Holden","sequence":"additional","affiliation":[{"name":"Department of Biochemistry University of Wisconsin Madison Wisconsin"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,7,23]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrmicro3380"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10295-013-1389-9"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/1751-7915.12123"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrmicro3496"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1039\/C6NP00025H"},{"key":"e_1_2_5_7_1","doi-asserted-by":"crossref","first-page":"90","DOI":"10.1016\/S1016-8478(23)13203-1","article-title":"The ribostamycin biosynthetic gene cluster in Streptomyces ribosidificus: comparison with butirosin biosynthesis","volume":"20","author":"Subba B","year":"2005","journal-title":"Mol Cells"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/tcr.201500210"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0076-6879(09)04620-5"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0969-2126(00)00085-X"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/prot.21076"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/ja.2009.76"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M505730200"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1107\/S0021889807021206"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1107\/S0907444904019158"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1107\/S0907444910007493"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1107\/S0907444996012255"},{"key":"e_1_2_5_18_1","doi-asserted-by":"publisher","DOI":"10.1006\/jmbi.1993.1351"}],"container-title":["Protein Science"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fpro.3221","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/pro.3221","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,6,25]],"date-time":"2024-06-25T09:04:55Z","timestamp":1719306295000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/pro.3221"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,7,23]]},"references-count":17,"journal-issue":{"issue":"9","published-print":{"date-parts":[[2017,9]]}},"alternative-id":["10.1002\/pro.3221"],"URL":"https:\/\/doi.org\/10.1002\/pro.3221","archive":["Portico"],"relation":{},"ISSN":["0961-8368","1469-896X"],"issn-type":[{"value":"0961-8368","type":"print"},{"value":"1469-896X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,7,23]]}}}
