| 1 | Cloning and characterization of the gene cluster required for beauvericin biosynthesis in Fusarium proliferatum显示文摘Beauvericin, a cyclohexadepsipeptide-possessing natural product with synergistic antifungal, insecticidal, and cytotoxic activities. We isolated and characterized the fpBeas gene cluster, devoted to beauvericin biosynthesis, from the filamentous fungus Fusarium proliferatum LF061. Targeted inactivation of the F. proliferatum genomic copy of fpBeas abolished the production of beauvericin. Comparative sequence analysis of the FpBEAS showed 74% similarity with the BbBEAS that synthesizes the cyclic trimeric ester beauvericin in Beauveria bassiana, which assembles N-methyl-dipeptidol monomer intermediates by the programmed iterative use of the nonribosomal peptide synthetase modules. Differences between the organization of the beauvericin loci in F. proliferaturm and B. bassiana revealed the mechanism for high production of beauvericin in F. proliferatum. Our work provides new insights into beauvericin biosynthesis, and may lead to beauvericin overproduction and creation of new analogs via synthetic biology approaches. | ZHANG Tao ZHUO Ying JIA XiaoPeng LIU JinTao GAO Hong SONG FuHang LIU Mei ZHANG LiXin | 2013 | Science China(Life Sciences)2013，56，7： | 3 |
| 2 | Beauvericin counteracted multi-drug resistant Candida albicans by blocking ABC transporters显示文摘Multi-drug resistance of pathogenic microorganisms is becoming a serious threat,particularly to immunocompromised populations.The high mortality of systematic fungal infections necessitates novel antifungal drugs and therapies.Unfortunately,with traditional drug discovery approaches,only echinocandins was approved by FDA as a new class of antifungals in the past two decades.Drug efflux is one of the major contributors to multi-drug resistance,the modulator of drug efflux pumps is considered as one of the keys to conquer multi-drug resistance.In this study,we combined structure-based virtual screening and whole-cell based mechanism study,identified a natural product,beauvericin(BEA)as a drug efflux pump modulator,which can reverse the multi-drug resistant phenotype of Candida albicans by specifically blocking the ATP-binding cassette(ABC)transporters;meantime,BEA alone has fungicidal activity in vitro by elevating intracellular calcium and reactive oxygen species(ROS).It was further demonstrated by histopathological study that BEA synergizes with a sub-therapeutic dose of ketoconazole(KTC)and could cure the murine model of disseminated candidiasis.Toxicity evaluation of BEA,including acute toxicity test,Ames test,and hERG(human ether-a-go-go-related gene)test promised that BEA can be harnessed for treatment of candidiasis,especially the candidiasis caused by ABC overexpressed multi-drug resistant C.albicans. | Yaojun Tong Mei Liu Yu Zhang Xueting Liu Ren Huang Fuhang Song Huanqin Dai Biao Ren Nuo Sun Gang Pei Jiang Bian Xin-Ming Jia Guanghua Huang Xuyu Zhou Shaojie Li Buchang Zhang Takashi Fukuda Hiroshi Tomoda SatoshiOmura Richard DCannon Richard Calderone Lixin Zhang | 2016 | Synthetic and Systems Biotechnology2016，1，3： | 1 |
| 3 | Discovery of tanshinone derivatives with anti-MRSA activity via targeted bio-transformation显示文摘Two potent anti-MRSA tanshinone glycosides(1 and 2)were discovered by targeted microbial biotransformation,along with rapid identification via MS/MS networking.Serial reactions including dehydrogenation,demethylations,reduction,glycosylation and methylation have been observed after incubation of tanshinone IIA and fungus Mucor rouxianus AS 3.3447.In addition,tanshinosides B(2)showed potent activities against serial clinical isolates of oxacillin-resistant Staphylococcus aureus with MIC values of 0.78 mg/mL.This is the first study that shows a significant increase in the level and activities of tanshinone glycosides relative to the substrate tanshinone IIA. | Wenni He Miaomiao Liu Pei Huang Wael M.Abdel-Mageed Jianying Han Jeramie D.Watrous Don D.Nguyen Wenzhao Wang Fuhang Song Huanqin Dai Jingyu Zhang Ronald J.Quinn Tanja Grkovi Houwei Luo Lixin Zhang Xueting Liu | 2016 | Synthetic and Systems Biotechnology2016，1，3： | 1 |
