Abstract

"ensaios de ciclização enzimática para homocisteína e cistationina". a presente invenção refere-se a um ensaio de ciclização enzimática para avaliação da quantidade de homocisteína e/ou cistationina em uma solução tal como sangue, derivados de sangue ou urina. o ensaio compreende as etapas de contato da solução contendo homocisteína e/ou cistationina para formar uma mistura de reação, com cbs, ou um seu derivado, l-serina, e cbl, ou um seu derivado, por um período de tempo suficiente para catalisar a conversão clínica da forma homocisteína em cistationina e a reconversão de cistationina em homocisteína com a produção de piruvato e amônia; determinação da quantidade de homocisteína e/ou amônia presente na mistura de reação; e determinação da quantidade de homocisteína e/ou cistationina presente na solução baseada na quantidade de piruvato e/ou amônia formada. vetores de expressão e procedimentos de isolamento para cbs, ou seus derivados, e cbi, ou seus derivados, são também providos, bem como kits de teste para realizar o ensaio. em modalidades preferidas, os ensaios podem ser realizados em 15 minutos ou menos, com um mínimo de uso de enzima.
