We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

OUTLINE

Tertiary Structure


Tertiary structure of protein is characterized by the “global” folding of a polypeptide chain [1] and has two domains in refined atomic model of glutamine synthetase from Salmonella typhimurium. Hydrophobic interaction is a major driving force determining the most tertiary structure of the proteins. [2] Hydrogen bonding <insert wiki showing the H.B> is crucial in stabilizing the tertiary structure as well. [3] Also, disulfide bonds <insert wiki showing the disulfide bonds of cysteine> between cysteine residues stabilize the tertiary structure. [4]

Glutamine synthetase from Salmonella has twenty three helix-helix interactions and is four different types of interactions. [5] on the protein residues and polar <polar wiki> (put color) region is represented by gray and light purple, and this characteristic strenthens the folding of proteins. And, it has charged region in the inside of molecules as well.

Usually, uncharged polar groups are classified as hydrophilic <insert wiki showing the hydrophilic> that is found on the outside of proteins. Also, amino acids with the character of acidic or basic side chains are polar, showing on the outside of molecules <insert wiki showing the polar>.
