Elemental sulfur (S8) was found to react with [(TMPA)CuI(CH3CN)]+ to form the trans-mu-1,2 end-on disulfide complex [(TMPA)Cu-S-S-Cu(TMPA)]2+. The X-ray structure of this centrosymmetric disulfide complex shows a Cu(1)-S(1) bond length of 2.280(2) A and a S(1)-S(1A) bond length of 2.044(4) A.

N-glycosylation is crucial in the process of wheat yellow mosaic virus (WYMV) infection, but changes in site-specific N-glycosylation of proteins during WYMV infection have not been well studied. In this study, we employed an intact glycopeptide approach to analyze mock- and WYMV-infected wheat plants. We found that most glycoproteins have N-glycans containing paucimannose or complex/hybrid chains.

Pentraxin-3 (PTX3) is a multifunctional pattern-recognition molecule that is essential for immune defense, pathogen recognition, and complement activation. PTX3 is stored as a monomer in neutrophil granules, and assembles into higher-order oligomers upon immune activation, thereby enhancing its antimicrobial function. The mechanism underlying this assembly remains elusive.

The study aimed to prepare complex gels of sonicated quinoa protein (QP) and polysaccharides, comparing the effects of different protein components and pH on gel properties. FTIR analysis demonstrated that the β-structure in protein at pH 7.0 was enhanced by ultrasonic treatment, which could promote the formation of a gel network.

This study investigated the effects of formulation and ultrasound on the processing properties and nutrient digestion of soy protein isolate (SPI)-egg white protein (EWP) emulsion gels. The incorporation of EWP significantly improved the texture properties and freeze-thaw stability through disulfide bonds and homogeneous networks in comparison to SPI emulsion gels. However, swelling ratio of emulsion gels at SPI:EWP ratios of 3:1 and 2:1 decreased due to disruption of SPI network continuity.

The use of green fluorescence protein (GFP) has advanced numerous areas of life sciences. An ultra-thermostable GFP (TGP), engineered from a coral GFP, offers potential advantages over traditional jellyfish-derived GFP because of its high stability. However, owing to its later discovery, TGP lacks the extensive toolsets available for GFP, such as heavy chain-only antibody binders known as nanobodies.
