A similar , less severe , metabolic disorder is congenital lactase deficiency 类似的,病症略轻为一点的代谢紊乱疾病是乳糖分解酶素缺乏症。
Some premature babies have a temporary form of lactose intolerance because their bodies are not yet producing lactase 一些早产的宝宝会暂时的有乳糖不耐受症状是因为他们体内还未开始分泌乳糖分解酶。
Elevated nitrogen deposition has the effects on the activities of enzymes responsible for decomposition of forest litter , which has attracted great attention worldwide 摘要氮沉降增加对森林凋落物分解酶产生的影响在世界范围受到关注。
According to the properties of litter substrate , the enzymes are classified into cellulolytic enzymes , ligninolytic enzymes , proteolytic enzymes and phosphatase 根据森林凋落物底物性质的不同,将凋落物分解酶分为纤维素分解酶类、木质素分解酶类、蛋白水解酶类和磷酸酶类。
Secondly , the hyaluronate lyase gene ( hyl ) was cloned into the vector puc19 by pcr using the total ona sample ofs . equi as template and partially sequenced , too Equi的总dna为模板,通过pcr方法,克隆了透明质酸分解酶基因( hyl ) ,测序后连接到表达载体pse380的trc启动子下游,构建表达质粒pse380 - hyl 。
