Ara h 1 trimer. Ara h 1 of the cupin superfamily is a trimer of bicupins, colored by the cupin domains (PDB:3SMH). The individual bicupins are colored pink, green, and blue, with Nterminal domains lightly shaded and the C-terminal domains a darker shade. Highlighted on the structure are the identified sites of glycosylation colored red (47) and glycation colored yellow. As technology improves, more glycation sites and AGE modifications may be identified [59]
