MAGIC Mn-salen mETALLOZYME: The design of an original, artificial, inorganic, complex-protein adduct, has led to a better understanding of the synergistic effects of both partners. The exclusive formation of sulfoxides by the hybrid biocatalyst, as opposed to sulfone in the case of the free inorganic complex, highlights the modulating role of the inorganic-complex-binding site in the protein. Artificial metalloenzymes based on the incorporation of Mn-salen complexes into human serum albumin display high efficiency and selectivity for sulfoxide production during sulfide oxidation. The reactions carried out by the artificial metallozymes are comparable to those carried out by natural biocatalysis. We have found that the polarity of the protein environment is crucial for selectivity and that a synergy between both partners of the hybrid results in the novel activity.
Study Question: Can a panel of plasma protein biomarkers be identified to accurately and specifically diagnose endometriosis?
Summary Answer: A novel panel of 10 plasma protein biomarkers was identified and validated, demonstrating strong predictive accuracy for the diagnosis of endometriosis.
What Is Known Already: Endometriosis poses intricate medical challenges for affected individuals and their physicians, yet diagnosis currently takes an average of 7 years and normally requires invasive laparoscopy. Consequently, the need for a simple, accurate non-invasive diagnostic tool is paramount.
Opportunistic pathogens, such as Aeromonas hydrophila, can cause damage to freshwater crayfish (Astacus leptodactylous) in some situations. In addition to direct damage to the body, microplastics (MPs) can also be responsible for transmitting pathogens to the animal. Accordingly, this research was prepared to investigate the effects of MP on the damage caused by A.
β-Glucosidase plays a pivotal role in transforming ginsenosides into specific minor ginsenosides. In this study, total ginsenosides from Panax notoginseng leaves were used as substrates to stimulate the growth of Aspergillus niger NG1306. Transcriptome analysis identified a β-glucosidase gene, Anglu04478 (1455 bp, 484 amino acids, 54.
In the present investigation, 13% ± 0.84 of the extracted and purified phycocyanin from Phormidium versicolor was obtained, with a purity of 0.69 following dialysis.
