The database initially consisted of 471 protein sequence families from the HSSP database, with an average of 47 aligned sequences per family. Each family contained a single known structure (parent) from the Brookhaven protein Data Bank. These were a subset of the PDBSelect-25 list, having no more than 25% sequence identity between any two ...
Major histocompatibility complex class I-related gene protein (MR1) is a non-classical MHC class I protein, that binds vitamine metabolites (intermediates of riboflavin synthesis) produced in certain types of bacteria. MR1 interacts with mucosal associated invariant T cells (MAIT). [5] [6]
Electron micrograph of in vitro–formed COPI-coated vesicles. Average vesicle diameter at the membrane level is 60 nm. COPI is a coatomer, a protein complex [1] that coats vesicles transporting proteins from the cis end of the Golgi complex back to the rough endoplasmic reticulum (ER), where they were originally synthesized, and between Golgi compartments.
A transport protein (variously referred to as a transmembrane pump, transporter, escort protein, acid transport protein, cation transport protein, or anion transport protein) is a protein that serves the function of moving other materials within an organism. Transport proteins are vital to the growth and life of all living things.
[1] [2] The transducer in this system is a heterotrimeric G protein, composed of three subunits: a Gα protein such as G i α, and a complex of two tightly linked proteins called Gβ and Gγ in a Gβγ complex. [1] [2] When not stimulated by a receptor, Gα is bound to GDP and to Gβγ to form the inactive G protein trimer.
The good news is that 1/2 cup of cooked white beans contains an impressive 500 mg of potassium, which is 11% of the Daily Value, according to the USDA. Related: 8 Foods With More Potassium Than a ...
Chemical Structure of Type I Collagen. Type I collagen has a triple-helical form which is caused by its amino acid composition. Its specific domain follows an order of G-X-Y In which the X and Y slots are occupied by any amino acid other than glycine however these slots are typically occupied by both hydroxyproline and proline, not in any particular order.

Walnuts are so beneficial that research has found that eating 1 to 2 ounces of these tasty nuts daily for two years lowered total cholesterol and LDL cholesterol by roughly 4%.
