    [Abstract] Mycobacterium tuberculosis (Mtb) is transmitted by aerosol and can cause serious bacterial infection in the lung that can be fatal if left untreated. Mtb is now the leading cause of death worldwide by an infectious agent. Characterizing the early events of in vivo infection following aerosol challenge is critical for ...

    [Abstract] Histones constitute the protein components of nucleosomes. Despite their small sizes, histones do not diffuse through the nuclear pore complex. Instead, they are transported to the nucleus by importins, either alone or in complex with histone chaperones. Determining the molecular size of the importin-histone complexes is key to understanding the ...

    [Abstract] It is important to experimentally determine how membrane proteins are integrated into biomembranes to unveil the roles of the integration factors, and to understand the functions and structures of membrane proteins. We have developed a reconstitution system for membrane protein integration in E. coli using purified factors, in which the ...
    Confocal and Super-resolution Imaging of RNA in Live Bacteria Using a Fluorogenic Silicon Rhodamine-binding Aptamer

    [Abstract] Genetically encoded light-up RNA aptamers have been shown to be promising tools for the visualization of RNAs in living cells, helping us to advance our understanding of the broad and complex life of RNA. Although a handful of light-up aptamers spanning the visible wavelength region have been developed, none of them have yet been reported to be ...
    A Sensitive Coupled Enzyme Assay for Measuring Kinase and ATPase Kinetics Using ADP-Specific Hexokinase

    [Abstract] Kinases and ATPases perform essential biological functions in metabolism and regulation. Activity of these enzymes is commonly measured by coupling ATP consumption to the synthesis of a detectable product. For most assay systems the ATP concentration during the reaction is unknown, compromising the precision of the assay.

    Using the ...
