Bovine QSOX1 sequence. The amino acid sequence of Quiescin sulfhydryl oxidase 1 precursor is shown. Peptides identified by MS/MS are underlined, yielding a total coverage of 59% over the 537 residues remaining after cleavage of the signal sequence (shown boxed). The cysteine residues from the two redox-active CxxC motifs are indicated in inverse font.
