WebApr 23, 2012 · In contrast, the N-terminal cysteines of the peptide building blocks, which are the ligation handles, are temporarily protected as thiazolidine rings (the 5-membered N, S heterocycle) and then selectively exposed when needed. WebApr 30, 2024 · Many redox regulated cysteines are cryptic and solvent exposed by changes in protein structure that were induced by EGF treatment. The novel finding that cryptic cysteines are redox regulated has important implications for how redox signaling networks are specified and regulated to minimize crosstalk. import hotmail to gmail
