It has been recently demonstrated that the major allergen of apricot is a protein of molecular mass (M-r) 9000 belonging to the family of Lipid Transfer Protein.

Apricot LTP is a 91 amino acids protein like peach and almond LTPs with a sequence identity of 91% and 94%, respectively.

Abstract
It has been recently demonstrated that the major allergen of apricot is a protein of molecular mass (M-r) 9000 belonging to the family of Lipid Transfer Protein. The aim of this study was the determination of the primary structure of apricot LTP by micro-sequencing and mass spectrometric analyses. Apricot LTP is a 91 amino acids protein like peach and almond LTPs with a sequence identity of 91% and 94%, respectively. Like for the peach LTP, out of the 25 amino acids forming the inner surface of the tunnel-like hydrophobic cavity in maize ns-LTP, 16 are identical and 7 similar in the apricot LTP, supporting the hypothesis of a similar function.File | Dimensione | Formato | |
