Deorphanizing solute carriers in for secondary uptake of xenobiotic compounds.

The exchange of small molecules between the cell and the environment happens through transporter proteins. Besides nutrients and native metabolic products, xenobiotic molecules are also transported, however it is not well understood which transporters are involved. In this study, by combining exo-metabolome screening in yeast with transporter characterization in oocytes, we mapped the activity of 30 yeast transporters toward six small non-toxic substrates.

Identification of transporters involved in aromatic compounds tolerance through screening of transporter deletion libraries.

Aromatic compounds are used in pharmaceutical, food, textile and other industries. Increased demand has sparked interest in exploring biotechnological approaches for their sustainable production as an alternative to chemical synthesis from petrochemicals or plant extraction. These aromatic products may be toxic to microorganisms, which complicates their production in cell factories.

Engineering Saccharomyces cerevisiae for the de novo Production of Halogenated Tryptophan and Tryptamine Derivatives.

The indole scaffold is a recurring structure in multiple bioactive heterocycles and natural products. Substituted indoles like the amino acid tryptophan serve as a precursor for a wide range of natural products with pharmaceutical or agrochemical applications. Inspired by the versatility of these compounds, medicinal chemists have for decades exploited indole as a core structure in the drug discovery process.

A clean in-frame knockout system for gene deletion in Acetobacterium woodii.

Acetogenic bacteria produce acetate following the fixation of CO via the Wood-Ljungdahl pathway. As such, they represent excellent process organisms for the production of novel chemicals and fuels from this waste greenhouse gas. Acetobacterium woodii is the model acetogen and numerous studies have been conducted investigating its biochemistry, gas consumption and use as a production chassis.

Engineering the oleaginous yeast Yarrowia lipolytica for high-level resveratrol production.

Resveratrol is a plant secondary metabolite with multiple health-beneficial properties. Microbial production of resveratrol in model microorganisms requires extensive engineering to reach commercially viable levels. Here, we explored the potential of the non-conventional yeast Yarrowia lipolytica to produce resveratrol and several other shikimate pathway-derived metabolites (p-coumaric acid, cis,cis-muconic acid, and salicylic acid).
