High-yield production of protopanaxadiol from sugarcane molasses by metabolically engineered Saccharomyces cerevisiae

Microbial Cell Factories, 2022
Background Ginsenosides are Panax plant-derived triterpenoid with wide applications in cardiovascular protection and immunity-boosting. However, the saponins content of Panax plants is fairly low, making it time-consuming and unsustainable by direct ...

Fabrication and Characterization of Graphene Microcrystal Prepared from Lignin Refined from Sugarcane Bagasse

Nanomaterials, 2018
Graphene microcrystal (GMC) is a type of glassy carbon fabricated from lignin, in which the microcrystals of graphene are chemically bonded by sp3 carbon atoms, forming a glass-like microcrystal structure.

Recombinant production of Paenibacillus wynnii  β-galactosidase with Komagataella phaffii

Microbial Cell Factories
Background The β-galactosidase from Paenibacillus wynnii (β-gal-Pw) is a promising candidate for lactose hydrolysis in milk and dairy products, as it has a higher affinity for the substrate lactose (low K M value) compared to industrially used β ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Recombinant production of acidophilic L-arabinose isomerase from Lentilactobacillus parakefiri in Bacillus subtilis

Microbial Cell Factories
Background The monosaccharide D-tagatose is a promising alternative to sucrose because of its similar sweetness and lower glycemic index. A novel L-arabinose isomerase (L-AI) from Lentilactobacillus parakefiri DSM 10551 (L-AI-Lp) has been biochemically ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
