We present a combined theoretical (molecular dynamics, MD) and experimental (differential scanning calorimetry, DSC) study of the effect of 7-nitrobenz-2-oxa-1,3-diazol-4-yl (NBD) acyl chain-labeled fluorescent phospholipid analogs (C6-NBD-PC and C12-NBD-PC) on 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) bilayers. DSC measurements reveal that <1 mol% of NBD-PC causes elimination of the pre-transition...
The outer membrane protein F (OmpF) is known to play an important role in the uptake of fluoroquinolone antibiotics by bacteria. In this study, the degree of binding of the fluoroquinolone antibiotic ciprofloxacin to OmpF in a lipid membrane environment is quantified using a methodology based on Förster resonance energy transfer (FRET). Analysis of the fluorescence quenching of OmpF is complex as...
