A Bacterial Sulfotransferase Catalyzes an Unusual Di‐Sulfation in Natural Products Biosynthesis

ChemBioChem, EarlyView.
Herein, a unique sulfotransferase, AdpST, is identified from the adp biosynthetic gene clusters (BGC) in Streptomyces davaonensis DSM101723 and demonstrates that AdpST possesses di‐sulfation activity, which is unprecedented for bacterial phosphoadenosine‐5’‐phosphosulfate (PAPS)‐dependent sulfotransferases. It is further shown that the adp BGC contains

Mining Thermophile Genomes for New PETases with Exceptional Thermostabilities Using Sequence Similarity Networks

ChemBioChem, EarlyView.
Targeted genome mining identified thermostable enzymes (PETases) that hydrolyze the commonly used plastic polymer polyethylene terephthalate (PET). Thermostable enzymes are identified from thermophilic microbial sources. Experimental results reveal enzymatic activity on authentic PET films, highlighting potential for industrial application.

Identification of key active site positions controlling the chemoselectivity of Aspergillus brasiliensis unspecific peroxygenase

ChemBioChem, Accepted Article.
Heme‐containing unspecific peroxygenases (UPOs) have catched significant attention as biocatalysts for oxidation reactions due to their ability to function without expensive nicotinamide cofactors. In our recent study, the UPO from Aspergillus brasiliensis (AbrUPO) was found to catalyze the aromatic hydroxylation of substituted benzenes, a feature that

Improving the Efficiency of a Bioreactor Equipped With Mixed‐Flow Impellers

Chemical Engineering &Technology, EarlyView.
The present work investigated the biological performance of mixed‐flow impellers. To the authors’ knowledge, this is the first experimental study on such impellers in a fermentation process using A. vinelandii, which was chosen as a microorganism due to its high oxygen demand.

In Vitro Psilocybin Synthesis by Co‐Immobilized Enzymes

Chemistry – A European Journal, EarlyView.
The drug candidate and psychedelic mushroom product psilocybin was produced by multienzyme‐charged beads in a biocatalytic cell‐free approach. Using immobilized fungal indolethylamine biosynthetic and additional bacterial enzymes, these beads turned over 4‐hydroxy‐l‐tryptophan to psilocybin.
