C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Biochemical Validation of a Third Guanidine Riboswitch Class in Bacteria

, 2017
Recently, it was determined that representatives of the riboswitch candidates called ykkC and mini-ykkC directly bind free guanidine. These riboswitches regulate the expression of genes whose protein products are implicated in overcoming the toxic ...

Modular Assembly of a Biocatalytic Material for Stereoselective C─Si Bond Formation

Chemistry – A European Journal, EarlyView.
A modular, carrier‐free enzyme foam derived from Rhodothermus marinus cytochrome c combines structural stability with catalytic efficiency for stereoselective C─Si bond formation. Streptavidin (STV)‐mediated protein crosslinking creates a robust, self‐supporting materials platform for next‐generation biocatalysis.

Influence of a Guanidine Riboswitch in Bacterial Cells [PDF]

, 2018
Bacteria live in environments containing complex ecologies of other microbes that communicate and survive through the action of a variety of small metabolic compounds. One common yet relatively unstudied metabolite is guanidine.

The role of Rho GTPases in facial morphogenesis

Developmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Growth of complete ammonia oxidizers on guanidine [PDF]

Guanidine is a chemically stable nitrogen compound that is excreted in human urine and is widely used in manufacturing of plastics, as a flame retardant and as a component of propellants, and is well known as a protein denaturant in biochemistry 1–3 ...

Smart Functional Hydrogels: Emerging Platforms for Thermal and Electrochemical Energy Harvesting and Conversion Systems

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogel exhibits versatile functions, including efficient thermogalvanic conversion under a temperature difference, and acting as a cooling layer/forming a thermally conductive nanoactive composite for thermovoltaic conversion. Additionally, its self‐healing and self‐powered flexibility play a key role in energy storage systems. The growing demand

Proteomic signatures of equine dental tooth tissues in ageing and disease

Equine Veterinary Journal, EarlyView.
Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Synthalin, Buformin, Phenformin, and Metformin: A Century of Intestinal “Glucose Excretion” as Oral Antidiabetic Strategy in Overweight/Obese Patients

Livers
After the first release of synthalin B (dodecamethylenbiguanide) in 1928 and its later retraction in the 1940s in Germany, the retraction of phenformin (N-Phenethylbiguanide) and of Buformin in the USA (but not outside) because of the lethal complication

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

Food Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.
