Reactive sulfur species: an emerging concept in oxidative stress. Experiments showed that Ero1p and the mammalian homologues ERO1(alpha) and ERO1(beta) are able to catalyze oxidation by coupling de novo disulfide formation to the reduction of oxygen to hydrogen peroxide (H2O2). Ero1p was shown to oxidize PDI, which allowed PDI to exchange disulfides on the protein. How do disulfide bonds affect protein structure? 181:1375-9

A similar increased reactivity was seen with HOSCN (k2 7.7105M1s1 for insulin, compared with ~103M1s1 for the model compounds), but not with HOBr. Notice that in the oxidized (disulfide) state, each sulfur atom has lost a bond to . Once all the hair bonds are intact and in alignment, you have . The formation of disulfide bonds is an important event in the folding of many proteins found in the cell envelope of E. coli. Review.

Cell. ISSN 2045-2322 (online). 8c,d). Epub 2022 Mar 14. Disulfides increase the stability of the protein and also regulate redox-dependent functions, and over the years, our ideas of how disulfides form in proteins have drastically changed. Annu. J Clin Biochem Nutr 48, 819, doi: 10.3164/jcbn.11-006FR (2011). k2 for reaction of HOCl with the acylic disulfide 3,3-dithiodipropionic acid (DTDPA) was determined as (1.70.1)105M1s1, consistent with previous results [(1.80.2)105M1s1 at 22C and pH 7.4]28. In fact, after some time, double knockout cells re-established normal ER redox conditions after a strong reductive challenge, albeit at a slower rate than in wild-type cells. This tells us that ERO1 is not as necessary in higher eukaryotes as it is in yeast and implies that there are other pathways to forming disulfide bonds.
