it is widely thought that bcl-2 family proteins regulate commitment to apoptosis primarily through their capacity to control the permeability of the mitochondrial outer membrane permeabilization (momp) triggers the release of multiple apoptogenic factors into the cytosol and, thereby apoptosis. various bcl-2 family members affect this key event of the apoptotic cascade in different ways, determ...

Reductively [3H]methylated 3H mitochondrial-outer-membrane vesicles from rat liver and vesicles where monoamine oxidase has been derivatized irreversibly by [3H]-pargyline have been deliberately miscompartmentalized by heterologous transplantation into hepatoma (HTC) cells by poly(ethylene glycol)-mediated vesicle-cell fusion. Fluorescein-conjugated mitochondrial-outer-membrane vesicles have al...

In contrast to typical membrane proteins that span the lipid bilayer via transmembrane alpha-helices, bacterial outer membrane proteins adopt a beta-barrel architecture composed of antiparallel transmembrane beta-strands. The topology of outer membrane proteins is difficult to predict accurately using computer algorithms, and topology mapping protocols commonly used for alpha-helical membrane p...

Outer membrane proteins of Gram-negative bacteria play key roles in antibiotic resistance. However, it is unknown whether outer membrane proteins that respond to antibiotics behave in a specific manner. The present study specifically investigated the differentially expressed outer membrane proteins of an antibiotic-resistant bacterium, Edwardsiella tarda, a Gram-negative pathogen that can lead ...
