Cysteine contributes to the three-dimensional structure of a protein by forming covalent bonds with an identical amino acid in another part of the protein.

<h3>What is the Cysteine Structure?</h3>
  • Covalent disulfide bonds form between the sulfhydryl (-SH) groups of cysteines in different parts of a protein are very important in determining the three-dimensional shape of the protein.
  • is a HOOC-CH-(NH2)-CH2-SH proteinogenic amino acid that is semi-essential. Cysteine's thiol side chain frequently functions as a nucleophile in enzyme processes.
  • The sign Cyz is occasionally used when a deprotonated catalytic residue is present.
  • The sign Cym can also be used to usually denote the deprotonated form.
  • The thiol is capable of being oxidized to produce the disulfide derivative cystine, which is crucial for many proteins' structural integrity. Cyx is sometimes used in this context. It carries the E identifier E920 when added to food.
  • The codons UGU and UGC encode the amino acid cysteine.
  • Cysteine and methionine, which contain sulfur, are more quickly oxidized than other amino acids.
