蓝藻是天然产物的多产生产者。对这些化合物形成的生物化学研究揭示了在其他微生物中没有或很少发现的令人着迷的机制。在本文中,我们调查了从淡水,海洋和陆地生境分离的蓝藻的生物合成途径。我们特别强调模块化非核糖体肽合成酶(NRPS)和聚酮合成酶(PKS)途径,并强调已阐明或可预测的单个产物的独特酶机制。我们进一步包括核糖体天然产物和蓝藻吸收紫外线的色素。从蓝藻途径的生化研究中获得的机制见解可以启发未来通过合成生物学方法设计生物活性化合物的概念发展。
Cyanobacteria are prolific producers of natural products. Investigations into the biochemistry responsible for the formation of these compounds have revealed fascinating mechanisms that are not, or only rarely, found in other microorganisms. In this article, we survey the biosynthetic pathways of cyanobacteria isolated from freshwater, marine and terrestrial habitats. We especially emphasize modular nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) pathways and highlight the unique enzyme mechanisms that were elucidated or can be anticipated for the individual products. We further include ribosomal natural products and UV-absorbing pigments from cyanobacteria. Mechanistic insights obtained from the biochemical studies of cyanobacterial pathways can inspire the development of concepts for the design of bioactive compounds by synthetic-biology approaches in the future.
