Study of molecular transport through a single nanopore in the membrane of a giant unilamellar vesicle using COMSOL simulation 04/12/2019
Abstract The antimicrobial peptide (AMP) magainin 2 induces nanopores in the lipid membranes of giant unilamellar vesicles (GUVs), as observed by the leakage of water-soluble fluorescent probes from the inside to the outside of GUVs through the pores. However, molecular transport through a single nanopore has not been investigated in detail yet and is studied […]
Binding of HasA by its transmembrane receptor HasR follows a conformational funnel mechanism 04/12/2019
Abstract HasR in the outer membrane of Serratia marcescens binds secreted, heme-loaded HasA and translocates the heme to the periplasm to satisfy the cell’s demand for iron. The previously published crystal structure of the wild-type complex showed HasA in a very specific binding arrangement with HasR, apt to relax the grasp on the heme and […]
Effects of bovine serum albumin (BSA) on the excited-state properties of meso -tetrakis(sulfonatophenyl) porphyrin (TPPS 4 ) 01/12/2019
Abstract To infer changes in the photophysical properties of porphyrins due to complexation with albumin, a combination of Z-scan and conventional spectroscopic techniques was employed. We measured the characteristics of excited states of meso-tetrakis(sulfonatophenyl) porphyrin bound to bovine serum albumin and observed that the binding reduces the intersystem crossing quantum yield and increases the internal […]
