Gram-positive bacteria express numerous membrane transporters that promote the efflux of various drugs, including many antibiotics, from the cell to the outer medium. Drug transporters can be specific to a particular drug, or can have broad specifici

Natural killer (NK) cells are the first lymphoid population to reconstitute the peripheral blood compartment of immunologically compromised bone marrow transplant (BMT) recipients. Recent data suggest that, among patients transplanted for leukemia, N

The Bacillus subtilis genome encodes two multidrug efflux transporters sharing 51% sequence identity: Bmr, described previously, and Blt, described here. Overexpression of either transporter in B. subtilis leads to a similar increase in resistance to

Multidrug transporters bind chemically dissimilar, potentially cytotoxic compounds and remove them from the cell. How these transporters carry out either of these functions is unknown. On the basis of crystal structures of the multidrug-binding domai

The Bacillus subtilis transcriptional regulator BmrR recognizes dissimilar hydrophobic cations and, in response, activates the expression of a multidrug transporter which expels them out of the cell. The structure of the inducer-binding domain of Bmr

Multidrug-efflux transporters demonstrate an unusual ability to recognize multiple structurally dissimilar toxins. A comparable ability to bind diverse hydrophobic cationic drugs is characteristic of the Bacillus subtilis transcription regulator BmrR

Patients presenting with a natural killer (NK) cell leukemia generally have a poor prognosis. NK cell tumors are generally resistant to numerous chemotherapeutic drugs and even combination chemotherapy usually results in only short term remissions. T

In the bacterium Bacillus subtilis, the DNA-binding regulatory protein, BmrR, activates transcription from the multidrug transporter gene, bmr, after binding either rhodamine or tetraphenylphosphonium. These two compounds, which have no structural si

The expression of the Bacillus subtilus multidrug-efflux transporter Bmr can be induced by two of its structurally dissimilar substrates, rhodamine 6G and tetraphenylphosphonium, through their direct interaction with the transcriptional regulator Bmr

Multidrug transporters pump structurally dissimilar toxic molecules out of cells. It is not known, however, if detoxification is the primary physiological function of these transporters. The chromosomal organization of the gene encoding the Bacillus
