Disulfide bond linkage between C288 and C575 as determined by MS/MS spectrum of tryptic/chymotryptic digests of the 70 kDa subunit of peroxynitrite-treated complex II. Chain A and Chain B represent peptides containing aa 568–577 and aa 287–291, respectively. A disulfide bond linking Chain A with Chain B is indicated in red. The sequence-specific ions are labeled as bnA (n = 2–9) for Chain A, y3B and b3B for Chain B on the spectrum. M indicates Chain A plus Chain B.
