Cysteine reduction
WebThere has been recurring debate in the proteomics community around their use, with concern over negative impacts that result from overalkylation (off-target, non-thiol sites) or incomplete reduction and/or S-alkylation of cysteine. This chapter integrates findings from a number of studies on different reduction and alkylation strategies, to ...

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.
