Lysenin: a sphingomyelin specific pore-forming toxin.
Sphingomyelin is a major sphingolipid in mammalian cells. Recent results indicate that sphingomyelin is a reservoir of lipid second messengers, ceramide and sphingosine-1-phosphate. Sphingomyelin is also a major component of sphingolipid and cholesterol-rich membrane domains (lipid rafts). Lysenin is a pore-forming toxin that specifically binds sphingomyelin. The binding of lysenin to sphingomy...

Combined electrostatics and hydrogen bonding determine intermolecular interactions between polyphosphoinositides.
Membrane lipids are active contributors to cell function as key mediators in signaling pathways controlling cell functions including inflammation, apoptosis, migration, and proliferation. Recent work on multimolecular lipid structures suggests a critical role for lipid organization in regulating the function of both lipids and proteins. Of particular interest in this context are the polyphospho...
متن کاملThe single-giant unilamellar vesicle method reveals lysenin-induced pore formation in lipid membranes containing sphingomyelin.
Lysenin is a sphingomyelin (SM)-binding pore-forming toxin. To reveal the interaction of lysenin with lipid membranes, we investigated lysenin-induced membrane permeation of a fluorescent probe, calcein, through dioleoylphosphatidylcholine(DOPC)/SM, DOPC/SM/cholesterol(chol), and SM/chol membranes, using the single-giant unilamellar vesicle (GUV) method. The results clearly show that lysenin fo...
متن کاملInductive Effect of Bioactive Intermolecular Hydrogen Bonding Complex of 1,2,4,5 –Tetrazine and Inorganic Acid by NMR and QTAIM
In this paper, NMR and QTAIM analysis for three substituted of T2SA complex was investigated in the gas and four solvents at DFT level. Intermolecular O–H…N hydrogen bonds between 1,2,4,5-Tetrazine and Sulphurous acids enhance the stability of complex.1,2,4,5-Tetrazine is a highly reactive diene for [4+2] inverse-Diels–Alder cycloaddition processes and an excellent precursor to attain the pyrid...
