Changes in protein profile during coagulation of latex from Carica papaya

Abstract

We describe the changes in peptide composition by SDS-PAGE analysis of latex from Carica papaya collected at various times after incision of the unripe fruit. The data show that during latex coagulation several peptides are processed in an orderly fashion.
