Abstract

L'invention concerne des compositions et des méthodes permettant d'analyser des analytes, de préférence, des analytes à petites molécules. Ces méthodes d'analyse utilisent, au lieu d'anticorps ou de molécules qui se lient aux analytes ou aux substrats cibles, des enzymes modifiées, appelées enzymes de piégeage par substrat. Ces enzymes modifiées retiennent une affinité de liaison ou présentent une affinité de liaison améliorée pour un substrat ou un analyte cible, mais elles présentent une activité catalytique atténuée par rapport au substrat ou à l'analyte. L'invention concerne également ces enzymes modifiées, et notamment, des S-adénosylhomocystéine (SAH) hydrolases mutantes, retenant sensiblement une affinité de liaison ou présentant une affinité de liaison améliorée pour l'homocystéine ou la S-adénosylhomocystéine, mais présentant une activité catalytique atténuée. L'invention concerne en outre des conjugués des enzymes modifiées et une substance auxiliaire, tel que des agents assistant à la purification ou à la liaison sur un support solide.
