Deacetylation of ACLY Mediates RNA M6A‐Modification of NOXA and Promotes Chemoresistance of Colorectal Cancer

Advanced Science, EarlyView.
This study investigates the deacetylation of ACLY at K978 acts as a novel risk in colorectal cancer chemoresistance. The deacetylation of K978 induces ACLY relocation to the nucleus and promotes its binding to RBM15, a m6A methylation modification “writer”.

Biochemical Characterization of a Bifunctional Enzyme Constructed by the Fusion of a Glucuronan Lyase and a Chitinase from Trichoderma sp.

Life, 2020
Bifunctional enzymes created by the fusion of a glucuronan lyase (TrGL) and a chitinase (ThCHIT42) from Trichoderma sp. have been constructed with the aim to validate a proof of concept regarding the potential of the chimera lyase/hydrolase by analyzing ...

Biosynthesis of H2S and Siderophores Targeting Gram‐Negative Bacterial Resistance to Reactive Oxygen Species

Advanced Science, EarlyView.
Discover how Gram‐negative bacteria develop resistance to reactive oxygen species, and how scientists aim to overcome this challenge. Abstract Reactive oxygen species (ROS) are a promising alternative bactericide. However, it is questioned that bacteria can potentially develop resistance to ROS, similar to their resistance against antibiotics and ...

Isolation and identification of an alginate lyase-producing marine bacterium strain and its enzymological characteristics

浙江大学学报. 农业与生命科学版, 2013
Alginate polysaccharide produced by marine brown algae or certain Gram-negative bacteria is a linear anionic binary copolymer of β-D-mannuronic acid (M) and α-L-guluronic acid (G) residues. Alginate lyase (EC 4.2.2.3; EC 4.2.2.11), also known as alginase

PSMD14‐Mediated LDHA Deubiquitination Upregulates ACLY Expression via H3K18 Lactylation to Promote Lipid Synthesis and Pancreatic Cancer Progression

Advanced Science, EarlyView.
This study investigates the expression and functional role of the deubiquitinase PSMD14 in PC, with a focus on the mechanism by which it promotes lactate accumulation–induced histone lactylation, thereby driving aberrant lipid metabolism. These findings establish that dual targeting of PSMD14 and the glycolysis–lactylation signaling axis may represent ...

Encapsulated Escherichia coli in alginate beads capable of secreting a heterologous pectin lyase

Microbial Cell Factories, 2005
Background Production of heterologous proteins in the E. coli periplasm, or into the extracellular fluid has many advantages; therefore naturally occurring signal peptides are selected for proteins translocation.

Minimizing acetate formation in E. coli fermentations [PDF]

, 2007
Escherichia coli remains the best established production organisms in industrial biotechnology. However, during aerobic fermentation runs at high growth rates, considerable amounts of acetate are accumulated as by-product.

A Refined Adaptive Laboratory Evolution Strategy With Biosensor‐Assisted Selection Resolves the Tolerance–Efficiency Trade‐Off in Toxic Chemical Biosynthesis

Advanced Science, EarlyView.
This study presents a refined adaptive laboratory evolution (ALE) strategy to resolve the trade‐off between tolerance and biosynthetic efficiency in toxic chemical production. Combining in vivo mutagenesis, microdroplet‐based evolution, and biosensor‐assisted selection, this strategy rapidly yields robust “win‐win” phenotypes.

Cupin‐Type Dimethylsulfoniopropionate Lyase from Pelagibacter ubique (DddKPu) Catalyzes Aza‐Michael Addition of Primary and Secondary Amines to Acrylic Acid

Angewandte Chemie, EarlyView.
A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.
