Cysteines are one of the most rarely used amino acids, but when conserved in proteins they often play critical roles in structure, function, or regulation. (hindawi.com)
Indeed, it has been demonstrated that cysteines are characterized by the most extreme conservation pattern, being highly conserved in functional positions of proteins but poorly conserved otherwise [ 5 ]. (hindawi.com)
Within an individual protein there may be a number of cysteines which could allow for multiple thiol modifications. (hindawi.com)
Cysteines often form part of active sites, allowing for the protein to be switched on or off depending on redox state. (hindawi.com)
In proteins where cysteine is not within the active site, activity can be modulated by changing conformation or by influencing its regulatory role, for example, iron sulfur complexes (ISCs) in aconitase possess cysteines required for its activity [ 7 ]. (hindawi.com)
Allosterically regulated proteins that require an activator are sometimes based on a thiol exchange interaction involving cysteines, for example, pyruvate kinase uses fructose bisphosphate (FBPs) as a heterotrophic activator and it contains a cysteine in its FBP binding site [ 8 ]. (hindawi.com)
