A...In chemistry, a disulfide refers to a functional group with the structure R−S−S−R′. The linkage is also called an SS-bond or sometimes a disulfide bridge and is usually derived by the coupling of two thiol groups. In biology, disulfide bridges formed between thiol groups in two cysteine residues are an important component of the secondary and tertiary structure of proteins.INTRODUCTION. Disulfide bonds—covalent crosslinks between thiol groups of two cysteine residues—are well-recognized factors of protein stability that can also play a substantial role in function and regulation according to the recent studies ().Various experimental strategies, computational approaches, and empirical design rules were proposed to introduce non-native disulfide bonds intoIdentify the true statements regarding disulfide bridges (disulfide bonds).

Disulfide bonds are required for the stability and function of a large number of proteins. Recently, the results from genome analysis have suggested an important role for disulfide bonds concerning the structural stabilization of intracellular proteins from hyperthermophilic Archaea and Bacteria, contrary to the conventional view that structural disulfide bonds are rare in proteins from Archaea.Disulfide bridges are important to primary and tertiary structure, not quaternary b.

A disulfide bridge forms between two cysteine residues. d.Post-translational modification (PTM) refers to the covalent and generally enzymatic modification of proteins following protein biosynthesis.Proteins are synthesized by ribosomes translating mRNA into polypeptide chains, which may then undergo PTM to form the mature protein product. PTMs are important components in cell signaling, as for example when prohormones are converted to hormones.

Concepts and reasonA disulphide bond is also termed as disulphide bridge or an S-S bond. The disulphide bond is a covalent bond derived from two thiol groups because of oxidation of sulfhydryl groups. This oxidation process results in the formation of solid protein dimers, polymers, and their complexes in which the sulfide bonds helps in protein folding.

FundamentalsThe technique of oxidation of sulfhydryl groups mostly occurs with thiol team of cysteine and the formation of an S-S bond is as follows:

Answer:

Disulfide bond can happen between only cysteine residues as two thiol functional groups are required to form a disulfide bond.

Explanation:Only the cysteine is in a position to forming the disulphide bond and thus, it may possibly achieve this with most effective other cysteine workforce however now not with another amino acid. These bonds are liable for stabilizing the globular construction of the protein and those are the strongest of all bonds that a protein can possess.The skill of the protein to fold and remain solid inside its respective conformation is because of those forces which are protecting the proteins. Disulphide bonds are used for plenty of processes which come with DNA replication, protein folding in E.coli etc.

Disulphide bonds can exist between two amino acid residues on other chains and stabilize the structure of the protein.

Explanation:Disulphide bonds may also be shaped intramolecularly and intermolecularly. The intramolecular disulphide bonds happens inside a polypeptide chain and are liable for stabilization of tertiary buildings, whereas the intermolecular disulphide bond occurs between the polypeptide chains and these are meant to stabilize the quaternary buildings of the proteins.Most of cyclic peptides are shaped between the disulfide bonds and as a result, the denaturation of this cyclic peptide is determined by the stability of the disulfide bonds. Intracellular proteins lack disulfide bonds, while extracellular proteins ceaselessly have a number of of them.Importance of disulfide bond: Proteins is not going to have pharmacological or enzymatic job with out the existence of disulfide bonds and this bond confers steadiness to express conformations of proteins such as enzyme Ribonuclease and structural protein equivalent to keratin.
