Lactacystin is an irreversible proteasome inhibitor isolated from Streptomyces lactacystinicus. Despite its importance for its biological activity, the biosynthesis of lactacystin remains unknown. In this study, we identified the lactacystin biosynthetic gene cluster by gene disruption and heterologous expression experiments.

Tripterifordin and neotripterifordin are important ent-kaurane diterpenoids in the Chinese medicinal herb Tripterygium wilfordii, possessing significant anti-HIV(human immunodeficiency virus) activity. On the basis of elucidating the natural biosynthetic pathways of these compounds, heterologous production with microbial cell factories can help to alleviate the reliance on plant resources and provide abundant raw materials for sustainable production. TwKO is the first CYP450 enzyme involved in the biosynthesis of tripterifordin and neotripterifordin.

An endoplasmic reticulum-localized Cu transporter, PhHMA5II1, interacts with copper chaperones and plays an important role in Cu detoxification in petunia. Copper (Cu) is an essential element for plant growth but toxic when present in excess. In this study we present the functional characterization of a petunia (Petunia hybrida) P-type heavy-metal ATPases (HMAs), PhHMA5II1.

Background: Streptomyces roseochromogenes NRRL 3504 produces clorobiocin, an aminocoumarin antibiotic that inhibits DNA replication. No other natural products have been isolated from this bacterium so far, despite the presence of a rich repertoire of specialized metabolite biosynthesis gene clusters (smBGCs) within its genome. Heterologous expression of smBGCs in suitable chassis speeds up the discovery of the natural products hidden behind these sets of genes.
