Table II. Summary of DSSO-interlinked peptides of the yeast 20 S proteasome complex identified by LC MSⁿ.

All of the interlinked peptides displayed characteristic fragment pairs and were identified by Batch-Tag, MS-Bridge, and Link-Finder. AA, amino acid; Mod., modification.

^† Mature sequence from crystal data was used for data analysis.

^‡ They were identified from different fragment pair ions by MS³.

* Peptide fragments containing these sites were not sequenced by MS³.
