Characterization of grapes glycoproteins from native vines of Campania

Grapevine (Vitis vinifera L.) cultivars have recently been subjected to extensive ge-nomic and proteomic studies because of their economic importance worldwide for both fruit and beverage. In particular, glycoproteins from grape berries are believed to be important in sev-eral technological, oenological and allergological processes due to their physico-chemical properties. This thesis is focused on glycoproteins characterization, starting from proteic mate-rial extracted from grape samples at different states of ripening, collected in Cam-pania vines. Analysis of glycoproteins by advanced tandem mass spectrometry methodologies, using CID (collision induced dissociation) and ETD (electron transfer dissociation) fragmentation techniques were performed.
