From: Rattusin structure reveals a novel defensin scaffold formed by intermolecular disulfide exchanges
(a) Trypsin digestion and LC-MS analysis of refolded rattusin (r-RTSN). Trypsin cleavage sites are indicated by arrows on the sequence of RTSN. The digested peptide fragments were separated by RP-HPLC and their masses were analyzed by LC-MS and indicated on each peak (F1~4). (b) Peptide sequence and SS bond structure of the fragment proposed by mass analysis and primary sequence of RTSN. The proposed SS bond structure of F4 fraction is either F4-1 or F4-2.
