果胶和木聚糖是存在于自然界中非常丰富的可再生资源,但有时这些资源并没有得到很好地发掘和利用,反而造成了环境污染。有效地转化和利用这类丰富的可再生资源需要多种酶的共同参与,其中α-L-阿拉伯呋喃糖苷酶起着非常重要的作用,是本课题的研究重点。它减少阿拉伯糖侧枝产生的空间位阻,使得内切型酶更易结合和分解聚糖主链,从而大大增加水解效率。本研究主要包括以下四个部分。

微生物来源的天然产物在现代药物研发过程中起着关键作用,尤其是在肿瘤,感染,脂代谢失调以及免疫缺陷疾病的治疗过程中,次生代谢产物一直被证明是新型治疗药物以及先导化合物的持久而有效的来源(J.Nat.Prod.2012,75,311).随着基因组测序技术的飞速发展,多种微生物的全基因组信息已经被阐明,但研究发现,在正常实验室培养条件下,微生物体内大部分次生代谢基因处于"沉默"状态,即低表达或者不表达,
