Orientations Of Proteins In Membranes Database
Orientations of Proteins in Membranes (OPM) database provides spatial positions of membrane protein protein structure, structures with respect to the lipid bilayer. Positions of the proteins are calculated using an Implicit solvation, implicit solvation model of the lipid bilayer. The results of calculations were verified against experimental studies of spatial arrangement of transmembrane protein, transmembrane and peripheral membrane protein, peripheral proteins in membranes. Proteins structures are taken from the Protein Data Bank. OPM also provides structural classification of membrane-associated proteins into families and superfamilies, membrane topology, quaternary structure of proteins in membrane-bound state, and the type of a destination Biological membrane, membrane for each protein. The coordinate files with calculated membrane boundaries are downloadable. The site allows visualization of protein structures with membrane boundary planes through Jmol. The database w ...

Proteins
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid ...

Jmol
Jmol is computer software for molecular modelling of chemical structures in 3 dimensions. It is an open-source Java viewer for chemical structures in 3D. The name originated from ''Jva (the programming language) + olcules, and also the mol file format. JSmol is an implementation in JavaScript of the functionality of Jmol. It can hence be embedded in web pages to display interactive 3D models of molecules and other structures without the need for any software apart from the web browser (''it does not use Java''). Both Jmol and JSmol render an interactive 3D representation of a molecule or other structure that may be used as a teaching tool, or for research, in several fields, e.g. chemistry, biochemistry, materials science, crystallography, symmetry or nanotechnology. Software Jmol is written in the programming language Java, so it can run on different operating systems: Windows, macOS, Linux, and Unix, as long as they have Java installed. It is free and open-source so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lipid Anchored Protein
Lipids are a broad group of organic compounds which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries, and in nanotechnology. Lipids are broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, multilamellar/unilamellar liposomes, or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks": ketoacyl and isoprene groups. Using this approach, lipids may be divided into eight categories: fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides (derived from condensation of ketoac ...

Alpha Helices
An alpha helix (or α-helix) is a sequence of amino acids in a protein that are twisted into a coil (a helix). The alpha helix is the most common structural arrangement in the secondary structure of proteins. It is also the most extreme type of local structure, and it is the local structure that is most easily predicted from a sequence of amino acids. The alpha helix has a right-handed helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O group of the amino acid that is four residues earlier in the protein sequence. Other names The alpha helix is also commonly called a: * Pauling–Corey–Branson α-helix (from the names of three scientists who described its structure) * 3.613-helix because there are 3.6 amino acids in one ring, with 13 atoms being involved in the ring formed by the hydrogen bond (starting with amidic hydrogen and ending with carbonyl oxygen) Discovery In the early 1930s, William Astbury showed that there were dras ...
