was prepared as a key synthon for the enzymatic synthesis of β(1→3)-glucan oligosaccharides, catalyzed by a mutated β(1→3)-glucanase (E231G) frombarley (Hordeum vulgare L.). A strategy was developed for enzymatic elongation of the β(1→3)-glucan chain from the reducing end, using a single glucoside acceptor. When β-glucoside phenyl disulfide was used as the acceptor, this methodology generated lam
制备了3 II - O-烯丙基-α-laminaribiososyl氟化物,作为酶合成β(1→3)-葡聚糖寡糖的关键合成子,该酶由大麦的突变的β(1→3)-葡聚糖酶(E231G)催化。大麦(Hordeum vulgare L.)。开发了一种策略,使用单个葡萄糖苷受体从还原端开始酶促延伸β(1→3)-葡聚糖链。当将β-葡萄糖苷苯基二硫化物用作受体时,该方法产生了在其还原和非还原端均可缀合的层状低聚糖。
