https://www.selleckchem.com/products/bgb-16673.html Alcohol dehydrogenases (ADHs) play key roles in the production of various chemical precursors that are essential in pharmaceutical and fine chemical industries. To achieve a practical application of ADHs in industrial processes, tailoring enzyme properties through rational design or directed evolution is often required. Here, we developed a secretion-based dual fluorescence assay (SDFA) for high-throughput screening of ADHs. In SDFA, an ADH of interest is fused to a mutated superfolder green fluorescent protein (MsfGFP), which could result in the secretion of the fusion protein to culture broth. After a simple centrifugation step to remove the cells, the supernatant can be directly used to measure the activity of ADH based on a red fluorescence signal, whose increase is coupled to the formation of NADH (a redox cofactor of ADHs) in the reaction. SDFA allows easy quantification of ADH concentration based on the green fluorescence signal of MsfGFP. This feature is useful in determining specific activity and may improve screening accuracy. Out of five ADHs we have tested with SDFA, four ADHs can be secreted and characterized. We successfully screened a combinatorial library of an ADH from Pichia finlandica and identified a variant with a 197-fold higher kcat /km value toward (S)-2-octanol compared to its wild type.Trimethoprim-sulfamethoxazole (TMP/SMX) combination is used for the prophylaxis of Pneumocystis pneumonia (PCP). Although TMP/SMX is frequently used in dermatology for cases treated with corticosteroids and/or immunosuppressants, it is often difficult to continue the administration of TMP/SMX due to adverse events. There are only a few reported studies on the prophylaxis of PCP in dermatology. This is the first review focused on adverse events of TMP/SMX among patients with dermatological diseases compared with previous reports. In this study, we retrospectively investigated 132 cases treated with TMP/SMX an
