Thiotemplated Polyketide Chain Fusion and Reductive Cyclization Build the Reactive Butenolide Core of Malleicyprol

open access: yesAngewandte Chemie, EarlyView.
Malleicyprol, a virulence factor of notorious animal and human pathogens of the Burkholderia pseudomallei (BP) group, results from the fusion of two individual polyketide chains. The noncanonical condensation domain of the PKS–NRPS hybrid synthetase BurF forms an ester bond, and the terminal reductase domain mediates a reductive chain release followed ...

Lysosomal Cathepsin S Escape Facilitates Near Infrared Light‐Triggered Pyroptosis Via an Antibody‐Indocyanine Green Conjugate

open access: yesAdvanced Science, EarlyView.
ICAM1 antibody‐bound ICG triggers tumor‐specific, caspase‐1‐independent pyroptosis via CTSS‐mediated GSDMD cleavage, activates antitumor immunity, and synergizes with anti–PD‐1 therapy, offering a non‐apoptotic strategy to overcome resistance in cancer treatment.

Unlocking Lactonase Enzymes as Biocatalysts for the Deracemisation of Chiral γ‐Thiolactones

open access: yesAngewandte Chemie, EarlyView.
The application of lactonase enzymes as biocatalysts still remains underexplored. This study discloses the biocatalytic activity of two lactonases in the deracemisation of chiral C3‐substituted‐γ‐thiolactones. The biocatalyst GcL catalyses the enzymatic kinetic resolution (EKR) of C3‐amide‐thiolactones, while the rationally engineered biocatalyst N9 ...

Epoxides and soluble epoxide hydrolase in cardiovascular physiology.

open access: yesPhysiological Reviews, 2012
Epoxyeicosatrienoic acids (EETs) are arachidonic acid metabolites that importantly contribute to vascular and cardiac physiology. The contribution of EETs to vascular and cardiac function is further influenced by soluble epoxide hydrolase (sEH) that ...

Genetic Impacts on the Structure and Mechanics of Cellulose Made by Bacteria

open access: yesAdvanced Science, EarlyView.
A genetic mutation in a protease of a cellulose‐overproducing evolved bacterium significantly affects the proteome, structure, and mechanical properties of bio‐fabricated cellulose pellicles. By overexpressing synthase proteins that build the cellulose‐forming biological machinery of the cell, the evolved bacterium generates dense, stiff, and strong ...

Enhancing Cold Adaptation of Bidomain Amylases by High‐Throughput Computational Engineering

open access: yesAngewandte Chemie, EarlyView.
This work uncovers molecular determinants of cold adaptation in bidomain amylases by combining MD simulations and biochemical assays, revealing that increased domain separation drives enhanced activity at low temperatures. Guided by this principle, high‐throughput in silico linker screening of mesophilic psA was performed, yielding variant psA121 with ...

An Amygdala‐hippocampus Circuit for Endocannabinoid Modulation of Anxiety Avoidance

open access: yesAdvanced Science, EarlyView.
This study employs three synapse‐specific endocannabinoids (eCB) probes to monitor dynamic eCB release, activate CB1Rs and knockdown 2‐AG biosynthesis enzymes in glutamatergic anterior basolateral amygdala ‐ ventral hippocampus (aBLA–vHPC) circuit. At aBLA–vHPC circuits, activation of CB1Rs reduce anxiety avoidance, and knockdown of eCB biosynthesis ...
