Background: Papaya (Carica papaya L.) is a popular climacteric fruit, undergoing various physico-chem. changes during ripening. Although papaya is widely cultivated and consumed, few studies on the changes in metabolism during its ripening process at the proteasome level have been performed. Using a newly developed TMT-LCMS anal., proteomes of papaya fruit at different ripening stages were investigated. Results: In total, 3220 proteins were identified, of which 2818 proteins were quantified. The differential accumulated proteins (DAPs) exhibited various biol. functions and diverse subcellular localizations. The KEGG enrichment anal. showed that various metabolic pathways were significantly altered, particularly in flavonoid and fatty acid metabolisms The up-regulation of several flavonoid biosynthesis-related proteins may provide more raw materials for pigment biosynthesis, accelerating the color variation of papaya fruit. Variations in the fatty acid metabolism- and cell wall degradation-related proteins were investigated during the ripening process. Furthermore, the contents of several important fatty acids were determined, and increased unsaturated fatty acids may be associated with papaya fruit volatile formation. Conclusions: Our data may give an intrinsic explanation of the variations in metabolism during the ripening process of papaya fruit.
