Engineering Dimensional Configuration of Single‐Atom S‐Cu‐S Sites as Reversible Electron Station for Enhanced Peroxidase‐Mimicking

Advanced Science, EarlyView.
L‐cysteine triggers auto‐assembly of POD‐like 3D biomimetic S‐Cu‐S single‐atom nanozymes on MoS2 (MoCC). MoCC shows 16.3‐fold higher catalytic velocity and 17.9‐fold greater affinity than HRP, enabling efficient •OH generation via enhanced electron inversion and transfer.

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

Advanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Microenvironment Self‐Adaptive Nanoarmor to Address Adhesion‐ and Colonization‐Related Obstacles in Impaired Intestine Promote Bacteriotherapy Against Parkinson's Disease

Advanced Science, EarlyView.
A microenvironment self‐adaptive nanoarmor is developed to effectively address the adhesion‐ and colonization‐related challenges posed by multiple physiological and pathological characteristics in the intestine. L. plantarum@MPN@CS showed significant therapeutic potential in treating Parkinson's disease (PD), a model for extraintestinal disorders, as ...

ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency

Advanced Science, EarlyView.
Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.
