In practice and despite Anfinsen’s dogma. the refolding of recombinant multiple SS-bonded proteins is famously difficult because misfolded species with non-native SS-bonds appear upon the oxidization of their cysteine residues. On the other hand. single SS-bond proteins are thought to be simple to refold because their cysteines have only one SS-bond partner. https://www.lightemupsequences.com/flash-price-Bearington-Willie-B-Mine-Plush-Valentines-Bear-10-Inches-and-Retired-special-buy/
