Sucrose synthase belongs to glycosyltransferases and is a reversible catalyst present in plants, which catalyzes the conversion of sucrose into fructose and UDP-G or ADP-G. Sucrose synthase localizes to the cytoplasm, plasma membrane, cell wall, vacuole and mitochondria of plants. Sucrose synthase regulates sugar metabolism, supports the development of taproots, fruits, seeds and vascular tissues, drives the synthesis of starch, cellulose and callose, and enhances nitrogen fixation capacity. Sucrose synthase mediates signal transduction in plant meristems. Sucrose synthase is associated with plant growth, anaerobic stress tolerance, as well as shoot apical meristem and leaf morphology; overexpression of this enzyme promotes plant growth, increases xylem size, and elevates cellulose and starch contents .

D-Histidine is an anti-biofilm agent that targets bacterial quorum sensing systems (such as RhlI/RhlR pathway) and has antibacterial activity. D-Histidine works by non-covalently binding to bacterial regulatory factors or copper ion complexes, selectively inhibiting bacterial biofilm formation and motility. D-Histidine downregulates quorum sensing-related gene expression, reduces the synthesis of virulence factors (such as alginate and proteases), and interferes with bacterial membrane stability, inhibiting biofilm formation, promoting the disintegration of mature biofilms, and enhancing antibiotic sensitivity. D-Histidine is also an efficient catalyst for the salt-induced peptide formation (SIPF) reaction, which promotes the condensation of amino acids to form dipeptides (such as dialanine and dilysine) by forming a complex with copper ions (Cu 2+) .

BP Fluor 405 Picolyl Azide is an advanced fluorescent probe that incorporatess a copper-chelating motif to raise the effective concentration of Cu(I) at the reaction site. The rate of the CuAAC reaction depends on the concentrations of all reagents, including copper, therefore raising the effective copper concentration at the reaction site dramatically increases the rate of CuAAC reaction without increasing the concentrations of azide reagent or copper. In addition, the use of picolyl azide instead of conventional azides allows for at least a tenfold reduction in the concentration of the copper catalyst without sacrificing the efficiency of labeling. In summary, the introduction of a picolyl moiety into an azide probe leads to a substantial increase in the sensitivity of alkyne detection. This is of special value for the detection of low abundance targets or where significant increase in signal intensity is desired.

4,407 compounds

Metabolism is the set of life-sustaining chemical reactions in organisms that maintain cell homeostasis. Metabolic pathways are enzyme-mediated biochemical reactions that lead to biosynthesis (anabolism) or breakdown (catabolism) of molecules including glucose metabolism, lipid metabolism and amino acid or protein metabolism within a cell or tissue. As catalysts, enzymes are crucial to metabolism as they allow a reaction to proceed more rapidly and tregulate the rate of a metabolic reaction. Due to the importance of metabolic balance in the organism, the abnormal function of metabolic enzymes often leads to the occurrence of a variety of metabolic diseases, such as diabetes, obesity, cardiovascular disease, etc.

MCE designs a unique collection of 4,407 metabolic enzymes related small molecules, which is an important tool for studying the metabolic activities of organisms and developing drugs for metabolic diseases.
