Aspects of the biological redox chemistry of cysteine: from simple redox responses to sophisticated signalling pathways

The last decade has witnessed an increased interest in cysteine modifications such as sulfenic and sulfinic acids, thiyl radicals, sulfenyl-amides and thiosulfinates, which come together to enable redox sensing, activation, catalysis, switching and cellular signalling...
