The gene clusters responsible for their production are often cryptic under laboratory growth conditions. Characterization of these clusters is therefore essential for the discovery of new microbial pharmaceutical drugs. Here, we report the identification of the previously uncharacterized nybomycin gene cluster from the marine actinomycete Streptomyces albus subsp. chlorinus through its heterologous expression. Nybomycin has previously been reported to act against quinolone-resistant Staphylococcus aureus strains harboring a mutated gyrA gene but not against those with intact gyrA. The nybomycin-resistant mutants generated from quinolone-resistant mutants have been reported to be caused by a back-mutation in the gyrA gene that restores susceptibility to quinolones. On the basis of gene function assignment from bioinformatics analysis, we suggest a model for nybomycin biosynthesis.<\/jats:p>","DOI":"10.3390\/md16110435","type":"journal-article","created":{"date-parts":[[2018,11,5]],"date-time":"2018-11-05T10:43:45Z","timestamp":1541414625000},"page":"435","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Heterologous Expression of the Nybomycin Gene Cluster from the Marine Strain Streptomyces albus subsp. chlorinus NRRL B-24108"],"prefix":"10.3390","volume":"16","author":[{"given":"Marta","family":"Rodr\u00edguez Est\u00e9vez","sequence":"first","affiliation":[{"name":"Pharmazeutische Biotechnologie, Universit\u00e4t des Saarlandes, 66123 Saarbr\u00fccken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maksym","family":"Myronovskyi","sequence":"additional","affiliation":[{"name":"Pharmazeutische Biotechnologie, Universit\u00e4t des Saarlandes, 66123 Saarbr\u00fccken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nils","family":"Gummerlich","sequence":"additional","affiliation":[{"name":"Pharmazeutische Biotechnologie, Universit\u00e4t des Saarlandes, 66123 Saarbr\u00fccken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1803-4976","authenticated-orcid":false,"given":"Suvd","family":"Nadmid","sequence":"additional","affiliation":[{"name":"Pharmazeutische Biotechnologie, Universit\u00e4t des Saarlandes, 66123 Saarbr\u00fccken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andriy","family":"Luzhetskyy","sequence":"additional","affiliation":[{"name":"Pharmazeutische Biotechnologie, Universit\u00e4t des Saarlandes, 66123 Saarbr\u00fccken, Germany"},{"name":"Helmholtz-Institut f\u00fcr Pharmazeutische Forschung Saarland, 66123 Saarbr\u00fccken, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"339","DOI":"10.1038\/ja.2014.1","article-title":"Oleamycins A and B: New antibacterial cyclic hexadepsipeptides isolated from a terrestrial Streptomyces sp.","volume":"67","author":"Raju","year":"2014","journal-title":"J.
