A tetramer (/ ˈ t ɛ t r ə m ər /) (tetra-, "four" + -mer, "parts") is an oligomer formed from four monomers or subunits. The associated property is called tetramery . An example from inorganic chemistry is titanium methoxide with the empirical formula Ti(OCH 3 ) 4 , which is tetrameric in solid state and has the molecular formula Ti 4 (OCH ...
The formation of the sorbitol dehydrogenase tetramer from its monomers via dimers. A tetrameric protein is a protein with a quaternary structure of four subunits (tetrameric). Homotetramers have four identical subunits (such as glutathione S-transferase ), and heterotetramers are complexes of different subunits.
This usually implies that the complex consists of different oligomerisation interfaces. For example, a tetrameric protein may have one four-fold rotation axis, i.e. point group symmetry 4 or C 4 . In this case the four interfaces between the subunits are identical.
In chemistry and biochemistry, an oligomer (/ ə ˈ l ɪ ɡ ə m ər / ⓘ) is a molecule that consists of a few repeating units which could be derived, actually or conceptually, from smaller molecules, monomers. [1] [2] [3] The name is composed of Greek elements oligo-, "a few" and -mer, "parts". An adjective form is oligomeric. [3]
The size of the cavity contributes to the size of the particle that the cavity can enclose, for example inorganic nanoparticles, nucleic acids, and even other proteins. [6] The interior or chamber portion of the protein cage is usually accessible through a pore which is located in between protein subunits.
A tetramer assay (also known as a tetramer stain) is a procedure that uses tetrameric proteins to detect and quantify T cells that are specific for a given antigen within a blood sample. [1] The tetramers used in the assay are made up of four major histocompatibility complex (MHC) molecules, which are found on the surface of most cells in the ...
Structure of Saccharomyces cerevisiae TRiC in the AMP-PNP bound state (PDB 5GW5). [1]T-complex protein Ring Complex (TRiC), otherwise known as Chaperonin Containing TCP-1 (CCT), [a] is a multiprotein complex and the chaperonin of eukaryotic cells.
The corneal endothelium is a single layer of endothelial cells on the inner surface of the cornea.It faces the chamber formed between the cornea and the iris. The corneal endothelium are specialized, flattened, mitochondria-rich cells that line the posterior surface of the cornea and face the anterior chamber of the eye.
