WebIt refers to the addition of an acetyl group from acetyl-CoA to the alpha-amino group of the first residue of a protein, often after the cleavage of the initiator methionine. The most commonly acetylated residues are glycine, alanine, serine or threonine. This reaction occurs in the cytosol. Cystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH2CH(NH2)CO2H)2. It is a white solid that is poorly soluble in water. As a residue in proteins, cystine serves two functions: a site of redox reactions and a mechanical linkage that allows proteins to retain their three-dimensional structure.
