Extraction of Lipids from Phospholipid Membranes by Steered Molecular Dynamics
نویسنده
چکیده
Steered molecular dynamics (SMD) simulations were employed to investigate the extraction step of the lipid head group cleavage reaction by human synovial phospholipase A2 (PLA2) by pulling a lipid molecule from a monolayer of dilauroyl-phosphatidyl-ethanolamin lipids into the active site of PLA2 and into the aqueous phase. The results of the simulations were compared to draw inferences about the forces that stabilize the lipids in the membrane and to understand the mechanism of lipid extraction by PLA2.

The effect of temperature on the binding affinity of Remdesivir and RdRp enzyme of SARS-COV-2 virus using steered molecular dynamics simulation
The fatal SARS-COV-2 virus appeared in China at the end of 2019 for the first time. This virus has similar sequence with SARS-COV in 2002, but its infection is very high rate. On the other hand, SARS-COV-2 is a RNA virus and requires RNA-dependent RNA polymerase (RdRp) to transcribe its viral genome. Due to the availability of the active site of this enzyme, an effective treatment is targeting ...
متن کاملThree new scorpion chloride channel toxins as potential anti-cancer drugs: Computational prediction of the interactions with hMMP-2 by docking and Steered Molecular Dynamics Simulations
Scorpion venom is a rich source of toxins which have great potential to develop new therapeutic agents. Scorpion chloride channel toxins (ClTxs), such as Chlorotoxin selectively inhibit human Matrix Methaloproteinase-2 (hMMP-2). The inhibitors of hMMP-2 have potential use in cancer therapy. Three new ClTxs, meuCl14, meuCl15 and meuCl16, derived from the venom transcriptome of Iranian scorpion, ...

The aim of this study was to analyse polar lipids of Candida species isolated from Ahwaz (Iran) by Fast Atom Bombardment Mass Spectrometry (FAB MS). Nine isolates of Candida Sp. were identified by growth at 45°C, production of chlamydoconidia on cornmeal agar, colonial colour on CHROMagar Candida, germ tube production and ID 32C kits. Then polar lipids were extracted from freeze-dried cult...
متن کاملMembranes serve as allosteric activators of phospholipase A2, enabling it to extract, bind, and hydrolyze phospholipid substrates.
Defining the molecular details and consequences of the association of water-soluble proteins with membranes is fundamental to understanding protein-lipid interactions and membrane functioning. Phospholipase A2 (PLA2) enzymes, which catalyze the hydrolysis of phospholipid substrates that compose the membrane bilayers, provide the ideal system for studying protein-lipid interactions. Our study fo...
