Correct folding of newly made proteins is made possible by several ER proteins including: ...

Protein biosynthesis

... biosynthesis The events following biosynthesis include protein folding and post-translational modification . During and after synthesis, ... native secondary and tertiary structures . This is known as protein folding . Many proteins undergo post-translational modification . This is may ...

Protein

Alpha helix

... of amino acid (n+4). Short polypeptides usually are not able to adopt the alpha helical structure, since the entropic cost associated with the folding of the polypeptide chain is too high. Some amino acids (called helix breakers ) like proline will disrupt the helical structure. Ordinarily, a ...

Cell growth

... Large cells that are primarily for nutrient storage can have a smooth surface membrane, but metabolically active large cells often have some sort of folding of the cell surface membrane in order to increase the surface area available for transport functions. Yeast cell size regulation The ...

Disulfide bond

Glycoprotein

... include glucose , glucosamine , galactose , galactosamine , mannose , fructose , and sialic acid . The sugar group can assist in protein folding or improve its stability. Glycoproteins are often used in proteins that are at least in part located in extracellular space (that is, outside the ...

Structural biology

... But variations on these methods are also used to watch nascent or denatured molecules assume or reassume their native states (see e.g. protein folding ). A third approach that structural biologists take to understanding structure is bioinformatics to look for patterns among the diverse ...

Tertiary structure

... physiological role inside a cell is known as the native state or sometimes the native conformation . A protein assumes tertiary structure by " folding ". An important type of chemical bond involved in stabilizing the tertiary structure of many proteins is the disulfide bond . One goal of ...
