Monomolecular films of cholesterol oxidase and S-Layer proteins
(Elsevier B.V., 2011-05-15)
Cholesterol oxidase (ChOx) is a flavoenzyme that catalyzes the oxidation of cholesterol to cholest-5-en-3-one and subsequently the isomerization to cholest-4-en-3-one. ChOx has been very commonly studied as the detection ...

On the chemistry of ion exchange in monomolecular layers of lipids
(1969)
The main purpose of this work has been to study further the association of cations and anions with cell membrane lipids, in particular with phosphatidylcholine. The adsorption of Ca2+ or SO4 2- to phosphatidylcholine ...

Thyroid hormones-membrane interaction: Reversible association of hormones with organized phospholipids with changes in fluidity and dipole potential
(Elsevier Ireland, 2013-09)
Differential scanning calorimetry (DSC), mixed monomolecular layers and fluorescence spectroscopy techniques were applied to investigate the effect of thyroid hormones (THs) on the biophysical properties of model membranes. ...
Membrane adsorption or penetration differentially modulates β-galactosidase activity against soluble substrates
(Elsevier Science, 2002-01)
We investigated if in complex environments, like those where β-galactosidase activity is usually assayed, the kinetics of hydrolysis against soluble substrates could be modulated through enzyme-surface interactions. Kinetic ...
Langmuir films at the oil/water interface revisited
(Nature Publishing Group, 2019-12)
We studied monomolecular layers at the oil/water interface (O/W int ) in a Langmuir interfacial trough using egg-yolk phosphatidylcholine (EPC) (the model phospholipid) and Vaseline (VAS) as oil phase. The temporal dynamics ...
Membrane topology modulates β-galactosidase activity against soluble substrates
(Elsevier Science, 2002-11-06)
The effect of bio-surfaces of contrasting curvature, on the kinetic parameters of ortho-nitrophenyl-β-D-galactopiranoside hydrolysis catalyzed by E. coli β-galactosidase, was investigated. The self-aggregating state and ...
Monomolecular adsorption on nanoparticles with repulsive interactions: a Monte Carlo study
(Royal Society of Chemistry, 2016-05)
In the present work, we study the adsorption of different monomolecular species on nanoparticles with different sizes and geometries using a grand canonical Monte Carlo method. These species are characterized by repulsive ...
Flunitrazepam induces geometrical changes at the lipid-water interface
(Elsevier Science, 2001-01-15)
Flunitrazepam (FNTZ) effects on molecular packing and surface curvature in artificial model membranes were investigated. FNTZ, from the subphase under dipalmitoylphosphatidylcholine (dpPC) monolayers at the air-water ...
