Process Optimization and Application of Lipase Immobilized on Phenol Amino Modified MCM-41

Shipin gongye ke-ji
In order to construct a new catalytic system of immobilized lipase and improve the stability of enzyme, the phenol amino modified ordered mesoporous material (MCM-41) was introduced for the study of lipase immobilization.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Biomimetic synthesis of vesicular covalent organic frameworks by gemini surfactants for in-situ enzyme cascade immobilization

Nature Communications
In nature, enzymes in biofilms often lack robustness and chemical functionality. Covalent organic frameworks (COFs) have emerged as a robust platform for enzyme immobilization, but mimicking biofilm structures for in-situ enzyme immobilization remains ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

Advanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.
