Cryptic cysteines
http://www.heldlab.org/research.html WebSep 9, 2024 · Since most cysteines are buried due to negative selection (101, 102), redox regulation of cryptic cysteines provides a plausible mechanism specifying the context-dependent selectivity of redox signaling pathways (Fig. 4). Additional connections between protein structure and cysteine oxidation are notable.
