Forms disulfide bonds. Disulfide bonds in proteins are formed between the thiol groups of cysteine residues by the process of oxidative foldingthe other sulfur containing amino acid methionine cannot form disulfide bondsa disulfide bond is typically denoted by hyphenating the abbreviations for cysteine eg when referring to ribonuclease a the cys26cys84 disulfide bond or the 2684 disulfide bond or. It is also one of the most effective methods for irreversible inactivation of disulfide proteins. The same functional group will undergo the same or similar chemical reactions regardless of the size of the molecule it is a part of.
Enzymatic reaction image will open in a new window. Challenges in the characterization of cyclic peptides containing disulfide bonds. Incorporation of hplc with esi ms ms lc ms and nmr to analyze cyclic peptides.
Chemical modification of disulfide bonds is commonly used for structural and functional analysis of proteins. In organic chemistry functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
