Prediction of the Human EP1 Receptor Binding Site by Homology Modeling and Molecular Dynamics Simulation

The prostanoid receptor EP1 is a G-protein-coupled receptor (GPCR) known to be involved in a variety of pathological disorders such as pain, fever and inflammation. These receptors are important drug targets, but design of subtype specific agonists and antagonists has been partially hampered by the absence of three-dimensional structures for these receptors. To understand the molecular interact...

Regioselectivity of CYP2B6: homology modeling, molecular dynamics simulation, docking.

Human cytochrome P450 (CYP) 2B6 activates the anticancer prodrug cyclophosphamide (CPA) by 4-hydroxylation. In contrast, the same enzyme catalyzes N-deethylation of a structural isomer, the prodrug ifosfamide (IFA), thus causing severe adverse drug effects. To model the molecular interactions leading to a switch in regioselectivity, the structure of CYP2B6 was modeled based on the structure of ...

Human butyrylcholinesterase polymorphism: Molecular modeling.

BACKGROUND Prolonged apnoea following injection of ester-containing myoralaxants was first described in 1953. Because a large part of administered succinylcholine is shortly hydrolyzed by plasma butyrylcholinesterase (BChE) under normal conditions, prolonged apnoea was attributed to deficiency in BChE. It was found that BChE deficiency was due to genetic variations. Human BChE gene shows a larg...

Investigation of Melting by Molecular Dynamics Simulation

The melting of a 64 ion microcrystal of KCI was studied by means of a molecular dynamics computer simulation. We used a central pair interaction with an inverse power law repulsion. The thermodynamics, kinetic and structural properties such as melting temperature, latent heat, mean square displacement, diffusion constant, radial distribution function and bond angle distribution are calculated. ...
