Abstract

L'invention concerne une technique qui permet de produire des analogues de protéines précurseurs bioadhésives renfermant de l'hydroxyproline. La technique consiste à construire des vecteurs renfermant des séquences d'ADN codant pour lesdits analogues et à les utiliser pour transformer un hôte microbien, de préférence E. Coli. Durant la croissance, l'hôte est mis en contact avec un milieu hypertonique renfermant de l'hydroxyproline, ce qui entraîne l'assimilation de cette dernière par la protéine précurseur bioadhésive et son incorporation dans ladite protéine durant la traduction. L'incorporation d'hydroxyproline dans les protéines précurseurs bioadhésives durant leur production est avantageuse en ce que la modification post-traductionnelle des protéines n'est pas nécessaire.
