The mechanism of translocation of matrix-targeted, cleavable preproteins across the mitochondrial outer membrane was studied using purified outer membrane vesicles. The N-terminal presequence interacts in a sequential and reversible fashion with two specific binding sites. The first one is provided by protease-sensitive receptors on the surface of the membrane (cis site); the second one is loca...
We study the relaxation dynamics of a compressible bilayer vesicle with an asymmetry in the viscosity of the inner and outer fluid medium. First we explore the stability of the vesicle free energy which includes a coupling between the membrane curvature and the local density difference between the two monolayers. Two types of instabilities are identified: a small wavelength instability and a la...
Bacterial outer membrane vesicle (OMV)-mediated delivery of proteins to host cells is an important mechanism of host-pathogen communication. Emerging evidence suggests that OMVs contain differentially packaged short RNAs (sRNAs) with the potential to target host mRNA function and/or stability. In this study, we used RNA-Seq to characterize differentially packaged sRNAs in Pseudomonas aeruginosa...
Nisin is a pore-forming antimicrobial peptide. The capacity of nisin to induce transmembrane movement of a fluorescent phospholipid in lipid vesicles was investigated. Unilamellar phospholipid vesicles that contained a fluorescent phospholipid (1-acyl-2-(6-[(7-nitro-2-1, 3-benzoxadiazol-4-yl)amino]caproyl)-sn-glycero-3-phosphocholine) in the inner leaflet of the bilayer were used. Nisin-induced...
