subject Description
ATP-binding cassette transporters (ABC transporters) are members of a transport system superfamily that is one of the largest and is possibly one of the oldest families with representatives in all extant phyla from prokaryotes to humans. ABC transporters often consist of multiple subunits, one or two of which are transmembrane proteins and one or two of which are membrane-associated ATPases. The ATPase subunits that utilize the energy of adenosine triphosphate (ATP) binding and hydrolysis to energize the translocation of various substrates across membranes, either for uptake or for export of the substrate. Most but not all uptake systems also have an extracytoplasmic receptor, a solute binding protein.

Statistics

Shown below are histograms for all MemProtMD entries in grey and for this collection only in blue. Densities for all entries and for this collection are individually normalised. Publication date, resolution and experimental_method are taken directly from the PDB record, whilst membrane thickness is derived from MemProtMD simulations.

Images

The following pre-rendered images show: distortions of the lipid bilayer, averaged across the entire simulation; positions of lipids in a representative snapshot of the simulation and contacts between lipids or solvent and the protein in either cartoon or surface representation. Rendering is performed using VMD's Tachyon renderer.

Distortions

Distortions show the average surface formed by lipid phosphate beads over the final 800 ns of simulation time. Red indicates a thinning of the bilayer (compared to bulk thickness), whilst blue indicates thickening.

Lipids

Coarse-grained lipids are shown with glycerol beads in yellow, phosphate beads in red and choline beads in blue. Atomistic lipids are coloured according to the CPK standard.

Contacts

Contacts show the average occupancy of the selected group within 6 Ă… of the protein over the final 800 ns of simulation time. Use the buttons below to select a representation.
