Abstract: Moenomycin inhibits bacterial growth by clocking the transglycosylase activity of class A penicillin-binding proteins (PBPs), which are key enzymes in bacterial cell wall synthesis. The binding affinities of moenomycin A with various truncated PBPs were compared showing that the transmembrane domain is important for moenomycin binding. Full-length class-A PBPs from 16 bacterial species were produced, and their binding activities showed a correlation with the antimicrobial activity of moenomycin against Enterococcus faecalis and Staphylococcus aureus. Moreover, a fluorescence anisotropy-based high-throughput assay was developed and used successfully for identification of transglycosylase inhibitors.

Abstract: An inverter with soft switching is used for a high step-up ratio and a high conversion efficiency. The inverter includes an isolation voltage-quadrupling DC converter and an AC selecting switch. The isolation voltage-quadrupling DC converter includes an active clamping circuit. By a front-stage converter circuit, a continuous half-sine-wave current is generated. By a rear-stage AC selecting switch, the half-sine-wave current is turned into a sine-wave current. Thus, electricity may be supplied to an AC load or the grid. The circuit is protected by isolating the low-voltage side from the high-voltage side. The conversion efficiency is high. The leakage inductance is low. The switch stress is low. The inverter is durable and reliable. Hence, the inverter is suitable for use in a photovoltaic system to increase the total conversion efficiency.
