Abstract

Micromonospora genus produces >700 bioactive compounds of medical relevance. In spite of its ability to produce high number of bioactive compounds, no genome sequence is available with comprehensive secondary metabolite gene clusters analysis for anti-microbial producing Micromonospora strains. Thus, here we contribute the full genome sequence of Micromonospora sp. HK10 strain, which has high antibacterial activity against several important human pathogens like, Mycobacterium abscessus, Mycobacterium smegmatis, Bacillus subtillis, Staphylococcus aureus, Proteus vulgaris, Pseudomonas aeruginosa, Salmonella and Escherichia coli. We have generated whole genome sequence data of Micromonospora sp. HK10 strain using Illumina NexSeq 500 sequencing platform (2×150bp paired end library) and assembled it de novo. The sequencing of HK10 genome enables identification of various genetic clusters associated with known- and probably unknown- antimicrobial compounds, which can pave the way for new antimicrobial scaffolds.

摘要

小单孢菌属产生了700多种具有医学相关性的生物活性化合物。尽管它有能力产生大量生物活性化合物,但对于产抗菌小单孢菌菌株,尚无进行全面次生代谢物基因簇分析的基因组序列。因此,在此我们提供了小单孢菌HK10菌株的全基因组序列,该菌株对几种重要的人类病原体具有高抗菌活性,如脓肿分枝杆菌、耻垢分枝杆菌、枯草芽孢杆菌、金黄色葡萄球菌、普通变形杆菌、铜绿假单胞菌、沙门氏菌和大肠杆菌。我们使用Illumina NexSeq 500测序平台(2×150bp双端文库)生成了小单孢菌HK10菌株的全基因组序列数据,并进行了从头组装。HK10基因组的测序能够鉴定与已知和可能未知的抗菌化合物相关的各种基因簇,这可为新的抗菌支架铺平道路。
