Molecular dynamics simulations of biotin carboxylase.
Biotin carboxylase catalyzes the ATP-dependent carboxylation of biotin and is one component of the multienzyme complex acetyl-CoA carboxylase that catalyzes the first committed step in fatty acid synthesis in all organisms. Biotin carboxylase from Escherichia coli, whose crystal structures with and without ATP bound have been determined, has served as a model system for this component of the ac...
متن کاملThe biotin carboxylase-biotin carboxyl carrier protein complex of Escherichia coli acetyl-CoA carboxylase.
Escherichia coli acetyl-CoA carboxylase (ACC) is composed of four different protein molecules. These proteins form a large but very unstable complex. Hints of a sub-complex between the biotin carboxylase (BC) and biotin carboxyl carrier protein (BCCP) subunits have been reported in the literature, but the complex was not isolated and thus the protein stoichiometry could not be determined. We re...
متن کاملMolecular dynamics simulations.
Molecular dynamics simulations have become a standard tool for the investigation of biomolecules. Simulations are performed of ever bigger systems using more realistic boundary conditions and better sampling due to longer sampling times. Recently, realistic simulations of systems as complex as transmembrane channels have become feasible. Simulations aid our understanding of biochemical processe...
متن کاملMolecular dynamics simulations
Large biological molecules are frequently represented by a single three-dimensional structure, but in reality, under physiological conditions, they are dynamic entities in constant motion. One important theoretical technique for analyzing both motions and energetics and the roles they play in macromolecular structure and function is a form of simulation termed molecular dynamics. The field of o...
متن کاملMolecular Dynamics Simulations
A tutorial introduction to the technique of Molecular Dynamics (MD) is given, and some characteristic examples of applications are described. The purpose and scope of these simulations and the relation to other simulation methods is discussed, and the basic MD algorithms are described. The sampling of intensive variables (temperature T , pressure p) in runs carried out in the microcanonical (NV...
