Fungal β-1, 3-glucanosyltransferases: A comprehensive review on classification, catalytic mechanism and functional role.

β-1,3-Glucans form the major carbohydrate component of fungal cell walls, playing a vital role in cell viability, stress response, virulence, and even healthy functions such as immuno-enhancement. The elongation and branching of β-1,3-glucans is a mystery. More evidence proved the β-1, 3-glucantransferases belonging to GH72 or GH17 family to branch and remodel the synthesized linear β-1, 3-glucan chain by cleaving its internal β-1, 3-linkage and transfer the cleaved fragment to the nonreducing end of another β-1, 3-glucan acceptor.

A Newly Predicted Magnetic TMB6 Monolayer for Efficient Nitrogen Fixation.

Developing electrocatalysts for the N reduction reaction (NRR) with high activity, high selectivity, and low cost is urgently required to enhance the NH yield rate. Based on first-principles calculations, we predict a series of new transition metal boride TMB (TM = Ti, V, Cr, Mn, Fe, and Co) monolayers and investigate their magnetoelectronic and electrocatalytic properties. The results reveal that VB and CoB favor ferromagnetic coupling, while TiB, CrB, MnB, and FeB display antiferromagnetic ordering.

The effect of switchable electronic polarization states on the electronic properties of two-dimensional multiferroic TMBr/GaSSe (TM = V-Ni) heterostructures.

Multiferroic van der Waals (vdW) heterostructures (HSs) prepared by combining different ferroic materials offer an exciting platform for next-generation nanoelectronic devices. In this work, we investigate the magnetoelectric coupling properties of multiferroic vdW HSs consisting of a magnetic TMBr (TM = V-Ni) monolayer and a ferroelectric GaSSe monolayer using first-principles theory calculations. It is found that the magnetic orderings in the magnetic TMBr layers are robust and the band alignment of these TMBr/GaSSe HSs can be altered by reversing the polarization direction of the ferroelectric layer.

Mechanisms of circular RNA degradation.

Circular RNAs (CircRNAs) are a class of noncoding RNAs formed by backsplicing during cotranscriptional and posttranscriptional processes, and they widely exist in various organisms. CircRNAs have multiple biological functions and are associated with the occurrence and development of many diseases. While the biogenesis and biological function of circRNAs have been extensively studied, there are few studies on circRNA degradation and only a few pathways for specific circRNA degradation have been identified.

The relationship between hnRNP C and cancers has been extensively studied, and dysregulation of hnRNP C has been found in many cancers. According to existing public data, hnRNP C could promote the maturation of new heterogeneous nuclear RNAs (hnRNA s, also referred to as pre-mRNAs) into mRNAs and could stabilize mRNAs, controlling their translation.

Effects of Gut Microbiota on Host Adaptive Immunity Under Immune Homeostasis and Tumor Pathology State.

Gut microbiota stimulate and shape the body's adaptive immune response through bacterial components and its active metabolites, which orchestrates the formation and maintenance of the body's immune homeostasis.

Regardless of significant results, the regulation of gut microbiota on adaptive immunity in immune homeostasis and tumors needs a more thorough understanding.
