Unfolding Individual Domains of BmrA, a Bacterial ABC Transporter Involved in Multidrug Resistance.

The folding and stability of proteins are often studied via unfolding (and refolding) a protein with urea. Yet, in the case of membrane integral protein domains, which are shielded by a membrane or a membrane mimetic, urea generally does not induce unfolding. However, the unfolding of α-helical membrane proteins may be induced by the addition of sodium dodecyl sulfate (SDS).

The Peripherally Membrane-attached Protein MbFACL6 of Mycobacterium tuberculosis Activates a Broad Spectrum of Substrates.

The infectious disease tuberculosis is one of the fifteen most common causes of death worldwide (according to the WHO). About every fourth person is infected with the main causative agent Mycobacterium tuberculosis (Mb). A characteristic of the pathogen is its entrance into a dormant state in which a phenotypic antibiotic resistance is achieved.
