Abstract

Selon l'invention, les sites de liaison de protéines liantes et de leurs partenaires de liaison sont caractérisés, au niveau de l'aminoacide individuel, par combinaison d'un marquage par échange d'hydrogène lourd (tritium ou deutérium) et d'une dégradation séquentielle (de préférence par carboxypeptidase) et analyse de fragments marqués dans des conditions d'échange ralenti. En marquant d'abord le partenaire de liaison et en marquant le site de liaison de la protéine indirectement (par échange à la surface de liaison), il est possible de différencier le site de liaison de segments allostériquement protégés de la protéine liante.
