In Escherichia coli, the DnaK/DnaJ chaperone can control the stability and activity of σ32, which is the key factor in heat shock response. Heterologous expression of eukaryotic molecular chaperones protects E. coli from heat stress. Here, we show that BAH1, an E3 ligase from plant that has a similar zinc finger domain to DnaJ, can perform block the effect of DnaK on σ32 in Escherichia coli. By constructing...
The fast growing evidences have indicated that the natural product osthole is a promising drug candidate for fighting several serious human diseases, for example, cancer and inflammation. However, the mode-of-action (MoA) of osthole remains largely incomplete. In this study, we investigated the growth inhibition activity of osthole using fission yeast as a model, with the goal of understanding the...
