Summary: This study evaluated the interaction between Cyprinus carpio cytochrome P450 and surfactants through homology modelling and molecular docking experiments. The in silico analysis revealed the prevalent hydrophobic interactions and potential oxidative stress induced by the binding of cytochrome P450 with the surfactants. In vivo analysis showed that exposure to sublethal concentrations of surfactants adversely affected the oxidative stress and antioxidant enzymes in the liver of Cyprinus carpio.

Summary: Rubiginones are part of the angucycline family and have been shown to enhance the cytotoxicity of vincristine against drug-resistant cancer cell lines. Through genome mining of Streptomyces sp. CB02414, new rubiginones were discovered and a biosynthetic pathway was proposed based on the production profiles of wild-type and mutant strains. This research paves the way for further studies on cytochrome P450-catalyzed oxidation of angucyclines and the development of novel compounds through combinatorial biosynthesis strategies.

Summary: Cytochrome P450s are heme-binding monooxygenases that catalyze functionalization of various bonds, including heteroatom oxidation and C-C bond cleavage. Despite their biotechnological potential, P450s require redox partners for chemical transformations. This review focuses on the role of P450s in antibiotic biosynthesis, specifically macrolides, aminocoumarin antibiotics, NRPSs antibiotics, and RiPPs antibiotics.

Summary: Protein enzymes have great potential in technological applications, and the design of enzyme-polymer assemblies using hydrogels shows promise in achieving better control of stability and enzymatic activity. Computational analysis reveals that hydrophobic interactions play a key role in promoting enzyme-polymer assemblies, leading to the optimal design of bioconjugate materials.

Summary: The study found that sex, race, and certain genetic polymorphisms can influence the pharmacokinetics and safety of dexketoprofen. However, there is currently no clear pharmacogenetic predictor that justifies individualization of therapy based on genotyping for dexketoprofen. Further research is needed to confirm the role of specific genetic polymorphisms in the pharmacokinetic variability of dexketoprofen.

Summary: The functions of Plasmodium malaria parasites' cytochrome c remain unclear. They express two distinct cytochrome c homologs, c and c-2, with little sequence similarity. Knockdown or knockout of cytochrome c-2 had little impact on parasite growth, indicating the reliance on the more conserved cytochrome c for mitochondrial function. Biochemical and structural studies showed that cytochrome c-2 has an unusually open active site and can bind exogenous small molecules. These findings provide important insights into the cytochrome functions in malaria parasites.

Summary: Cytochrome P450 enzymes are important oxidative enzymes in the human body, and they can metabolize various exogenous and endogenous substrates. By using CYP4F11, a cytochrome P450 monooxygenase, in the biotransformation, four biotransformation products were obtained, including two oxidative products and two acetylated/esterified products. Modeling experiments explained the different activities of CYP4F11 and CYP4F12 in oxidizing dialkylresorcinol 2.

Summary: In this study, we report the discovery of three new isoflavone dimers from Streptomyces cattleya and the identification of a cytochrome P450 monooxygenase, CYP158C1, which can catalyze the dimerization of isoflavones. CYP158C1 was also found to be capable of dimerizing plant-derived polyketides, such as flavonoids and stilbenes, providing new insights into P450-mediated biaryl coupling reactions in biosynthesis.

Summary: By validating the functions of two pairs of redox partners sourced from Mycobacterium smegmatis and comparing the efficiency of different biocatalytic systems, it was demonstrated that M. smegmatis is more efficient, robust, and cleaner in metabolites background when converting HTDKPs. Via this system, 12 novel HTDPKs were obtained, with five of them showing neuroprotective properties.

Summary: Pharmacogenetic variability in drug metabolism can affect patient vulnerability to side effects and therapeutic failure. This study introduces a systematic statistical methodology to estimate quantitative dose adjustments based on pharmacokinetic differences in pharmacogenetic subgroups. The methodology addresses the challenges of sparse data, incomplete information on phenotypic groups, and heterogeneity of study design. The results demonstrate the effectiveness of the modeling approach in predicting dose adjustments and considering uncertainty.

Summary: Research finds that RubB efficiently transfers electrons from cognate reductases to support bacterial CYPs activity, mutations on RubB surface do not significantly decrease CYPs activity, suggesting interactions are transient and nonspecific.

Summary: This study investigated the effect of intercellular adhesion molecule CLDN1 on the anticancer drug sensitivity of small-cell lung cancer (SCLC) cells. It was found that overexpression of CLDN1 decreased the sensitivity of SCLC cells to anticancer drugs and enhanced their migratory capacity through the activation of the TGF-81/EMT signaling pathway. Treatment with EMT inhibitors showed potential in overcoming the reduced sensitivity to anticancer drugs in CLDN1-overexpressing SCLC cells.
