obsolete peptide cross-linking via 2-amino-3-isothiazolidinone-L-serine (obsolete GO:0048109)
OBSOLETE. The chemical reactions and pathways resulting in the formation of a peptidyl cysteine-peptidyl serine cross-link through a process of forming first an intermediate cysteine sulfenic acid by peroxide oxidation, followed by condensation with the alpha-amido of the following serine residue and the release of water.
