The gram-negative bacterium Escherichia coli offers a mean for rapid, high yield, and economical production of recombinant proteins. However, high-level production of functional eukaryotic proteins in E. coli may not be a routine matter, sometimes it is quite challenging. Techniques to optimize heterologous protein overproduction in E. coli have been(More)
Real time investigation of protein folding, structure, and dynamics at high resolution in living cells, is the next major step in nano cell biology. However, there are a number of major hurdles that need to be overcome, such as coupled translation and folding, the intervention of chaperones and folding enzymes, translocation, export, and the targeting(More)
Cells can sense a myriad of mechanical stimuli. Mechanosensitive channel of large conductance (MscL) found in bacteria is a well-characterized mechanosensitive channel that rapidly responds to an increase in turgor pressure. Functional expression of MscL in mammalian cells has recently been demonstrated, revealing that molecular delivery or transport can be(More)
Generation of artificial cells provides the bridge needed to cover the gap between studying the complexity of biological processes in whole cells and studying these same processes in an in vitro reconstituted system. Artificial cells are defined as the encapsulation of biologically active material in a biological or synthetic membrane. Here, we describe a(More)
Dimerization of G protein-coupled receptors (GPCRs) represents a potential mechanism by which GPCR functions are regulated. Several resonance energy transfer (RET)-based methods have revealed GPCR homo- and heterodimerization. However, interpretation of an increase in FRET efficiency could be attributed to either dimerization/oligomerization events or(More)
The Gram-negative bacterium Escherichia coli offer a means for rapid, high-yield, and economical production of recombinant proteins. However, when preparing protein samples for NMR, high-level production of functional isotopically labeled proteins can be quite challenging. This is especially true for the preparation of triple-labeled protein samples in(More)
Human high-density lipoproteins (HDL) are protein/lipid particles of nanometer sizes. These nano particles are critical for transportation of the "bad cholesterol" from peripheral tissues back to the liver for clearance. An inverse correlation has been observed between the plasma HDL concentration and atherosclerosis. Furthermore, the HDL particle has also(More)
