Potential proteolytic processing of Vtg in rainbow trout

---

The potential fragmentation process can be estimated by the fact that a Vtg fragment is derived from another longer fragment that appears earlier and logically includes it. For instance, Spot338 appeared earlier than Spot53, and the former includes the latter, so it is possible that Spot338 is cleft to Spot53. Potential proteolytic processing of 45 Vtg-fragments of rainbow trout is summerized in this figure.
