3-Chloro-Abu and 4-chloro-Nva are biosynthetically incorporated into E. coli peptidyl-Pro cis-trans isomerase B, as substitutes for Val and Leu, respectively. The extent of incorporation is up to ~90%, and substituted protein is catalytically active. By contrast, 4-chloro-Val is not an effective replacement for Ile.
将3-氯-Abu和4-氯-Nva生物合成并入大肠杆菌肽基-Pro顺-反异构酶B中,分别替代Val和Leu。掺入的程度高达〜90%,并且取代的蛋白质具有催化活性。相比之下,4-氯-Val并不是Ile的有效替代品。
