is a rare genus of Actinobacteria that harbors a variety of secondary metabolite gene clusters and produces several interesting types of bioactive secondary metabolites. Recent efforts have partially elucidated the biosynthetic pathways of some of these bioactive natural products, suggesting the diversity and specificity of secondary metabolism within this genus. Here, we summarized the chemical structures, biosynthetic pathways, and key metabolic enzymes of the secondary metabolites isolated from strains. In-depth comparative genomic analysis of all six available high-quality genomes revealed that the majority (77%) of the biosynthetic gene cluster families of were untapped and identified homologues of key metabolic enzymes in the putative gene clusters, including cytochrome P450s, halogenases, and flavin-dependent -hydroxylases. The present study suggests that exhibits great potential to synthesize novel secondary metabolites, encodes a variety of valuable metabolic enzymes, and also provides valuable information for the targeted discovery and biosynthesis of novel natural products from .
是放线菌的一个稀有属,拥有多种次生代谢物基因簇,并产生几种有趣类型的生物活性次生代谢物。最近的研究工作部分阐明了其中一些生物活性天然产物的生物合成途径,表明该属内次生代谢的多样性和特异性。在此,我们总结了从菌株中分离出的次生代谢物的化学结构、生物合成途径和关键代谢酶。对所有六个可用的高质量基因组进行深入的比较基因组分析表明,该属的大多数(77%)生物合成基因簇家族尚未开发,并在假定的基因簇中鉴定出关键代谢酶的同源物,包括细胞色素P450、卤化酶和黄素依赖性β-羟化酶。本研究表明,该属在合成新型次生代谢物方面具有巨大潜力,编码多种有价值的代谢酶,也为从该属中靶向发现和生物合成新型天然产物提供了有价值的信息。
