What is the relevance of conserved cystein residues?

WebMultiple cysteines in the native protein structure present an obvious roadblock in achieving site-specificity, raising the need for additional steps to remove (i.e., by site-directed mutagenesis) or sterically block competing sites (Jager et al., 2005 ). WebCystine is the oxidized derivative of the amino acid cysteine and has the formula (SCH 2 CH (NH 2 )CO 2 H) 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.
