Abstract
Thiosulfate: cyanide sulfurtransferase (TST), also named rhodanese, is an enzyme widely distributed in both prokaryotes and eukaryotes, where it plays a relevant role in mitochondrial function. TST enzyme is involved in several biochemical processes such as: cyanide detoxification, the transport of sulfur and selenium in biologically available forms, the restoration of iron–sulfur clusters, redox system maintenance and the mitochondrial import of 5S rRNA. Recently, the relevance of TST in metabolic diseases, such as diabetes, has been highlighted, opening the way for research on important aspects of sulfur metabolism in diabetes. This review underlines the structural and functional characteristics of TST, describing the physiological role and biomedical and biotechnological applications of this essential enzyme.

Exhausted local lactate accumulation via injectable nanozyme-functionalized hydrogel microsphere for inflammation relief and tissue regeneration. Bioact Mater 2022; 12:153-168. [PMID: 35310385 PMCID: PMC8897073 DOI: 10.1016/j.bioactmat.2021.10.013] [Citation(s) in RCA: 35] [Impact Index Per Article: 17.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 09/11/2021] [Accepted: 10/10/2021] [Indexed: 12/15/2022] Open
Abstract
Local lactate accumulation greatly hinders tissue repair and regeneration under ischemic condition. Herein, an injectable microsphere (MS@MCL) for local lactate exhaustion was constructed by grafting manganese dioxide (MnO2) -lactate oxidase (LOX) composite nanozyme on microfluidic hyaluronic acid methacrylate (HAMA) microspheres via chemical bonds, achieving a long-term oxygen-promoted lactate exhaustion effect and a long half-life in vivo. The uniform and porous microspheres synthesized by microfluidic technology is beneficial to in situ injection therapy and improving encapsulation efficiency. Furthermore, chemical grafting into HAMA microspheres through amide reactions promoted local enzymatic concentration and activity enhancement. It was showed that the MS@MCL eliminated oxidative and inflammatory stress and promoted extracellular matrix metabolism and cell survival when co-cultured with nucleus pulposus cells (NPCs) in vitro. In the rat degenerative intervertebral disc model caused by lactate injection, MS@MCL showed a long-term therapeutic effect in reducing intervertebral height narrowing and preventing extracellular matrix (ECM) degradation as well as inflammatory damage in vivo. Altogether, this study confirms that this nanozyme-functionalized injectable MS@MCL effectively improves the regenerative and reparative effect in ischemic tissues by disposing of enriched lactate in local microenvironment. Exhausted local lactate accumulation via injectable hydrogel microsphere. Long-acting microfluidic hyaluronic acid microspheres. Manganese dioxide-lactate oxidase composited nanozyme via covalent bond. Promoted sustained release of nanozyme and maintained enzymatic activity.

Alfaiz FA. Molecular studies of immunological enzyme clumping factor B for the inhibition of Staphylococcus aureus with essential oils of Nigella sativa. J Mol Recognit 2021; 34:e2941.

Abstract
Essential oils from black cumin seeds (Nigella sativa) have largely been used in the manufacturing of nutraceuticals and functional food products due to the presence of a wide variety of bioactive compounds. However, their applications in the pharmaceutical sector have recently attracted interest and started blooming. The present research elucidates the in silico and in vitro efficacies of active leads from essential oil of N sativa against the human pathogenic bacterium Staphylococcus aureus. Biofilm development has become an inevitable situation in the health care sector. Lowering the efficacies of antimicrobial drugs is one of the vital ramifications that resulted in the emergence of multidrug resistance. Clumping factor B (clfB) of S aureus plays a key role in the human immune functions during pathogenesis. Through STRING analysis, the interacting protein partners of clfB were found to regulate biofilm pathway. Therefore, eight ligands from essential oil are docked with the critical clfB protein, which revealed p-cymene, thymoquinone and carvacrol as the robust ligands with highest binding affinity. Therefore, antibiofilm potential of N sativa essential oil at in vitro states was evaluated against S aureus. Further, real time PCR analysis showed that the expression of clfB and intercellular adhesion gene (icaA and icaD) was significantly altered upon treatment with essential oil. Altogether, the findings confirmed the antibiofilm efficacy of N sativa essential oil against S aureus. Hence, the essential oil from N. sativa was envisaged to be promising candidate to treat S aureus biofilm mediated infection.

Abstract
How the three-dimensional (3D) chiral environment affects the biocatalysis remains an important issue, thereby inspiring the development of a microenvironment that highly mimics the natural features of enzyme to guarantee enhanced biocatalysis. In this study, two gelators bearing d/l-phenylalanine as chiral centers are designed to construct the 3D chiral catalytic microenvironment for enhancing the biocatalysis of lipase. Such a microenvironment is programmed through chiral transmission of chirality from molecular chirality to achiral polymers. It shows that the chirality of the microenvironment evidently influences the catalytic efficiency of immobilized lipase inside the system, and the 3D microenvironment constructed by right-handed helical nanostructures can enhance the catalytic activity of lipase inside as high as 10-fold for catalyzing 4-nitrophenyl palmitate (NPP) to 4-nitrophenol (NP) and 1.4-fold for catalyzing lipids to triglycerides (TGs) in 3T3-L1 cells than that of the achiral microenvironment. Moreover, the 3D chiral microenvironment has the merits of good catalytic efficiency, high storage stability, and efficient recyclability. This strategy of designing a 3D chiral microenvironment suitable for biocatalysis will overcome the present limitations of enzymatic immobilization in traditional materials and enhance the understanding of biocatalysis.
