On the Coupling between Mechanical Properties and Electrostatics in Biological Membranes
Autor: Vanesa Viviana Galassi, Natalia Wilke
Publikováno v: Membranes, Vol 11, Iss 7, p 478 (2021)
Cell membrane structure is proposed as a lipid matrix with embedded proteins, and thus, their emerging mechanical and electrostatic properties are commanded by lipid behavior and their interconnection with the included and absorbed proteins, cytoskel

Hopanoids Like Sterols Form Compact but Fluid Films
Autor: Vanesa Viviana Galassi, Agustín Mangiarotti, Natalia Wilke, Rafael G. Oliveira, Mario G. Del Pópolo, Elida N Puentes
Publikováno v: Langmuir. 35:9848-9857
Hopanoids are pentacyclic molecules present in membranes from some bacteria, recently proposed as sterol surrogates in these organisms. Diplopterol is an abundant hopanoid that, similar to sterols, does not self-aggregate in lamellar structures when

Conformational changes, from β-strand to α-helix, of the fatty acid-binding protein ReP1-NCXSQ in anionic lipid membranes: dependence with the vesicle curvature
Autor: Vanesa Viviana Galassi, Guillermo G. Montich, Silvina R. Salinas
We studied the conformational changes of the fatty acid-binding protein ReP1-NCXSQ in the interface of anionic lipid membranes. ReP1-NCXSQ is an acidic protein that regulates the activity of the Na+/Ca2+ exchanger in squid axon. The structure is a fl

Publikováno v: Biophysical Journal. 102(3)
The fatty acid-binding protein ReP1 is a soluble protein that shows the common beta-barrel motif with two alpha-helix in the portal region. Its isoelectric point of 5.85 leads to net charge of −1 at neutral pH. Previous evidence of its interaction

Avian liver bile acid-binding protein (L-BABP) binds peripherically to anionic lipid membranes. We previously showed that in the absence of added salt the binding to 1,2-dimyristoyl-sn-glycero-3-phosphoglycerol (DMPG) occurs with changes in the secon
