一般說明

我们致力于为您提供更环保的替代产品,以符合“绿色化学的12项原则”的一项或多项原则要求。该产品针对纤维素乙醇研究进行了优化,可提高能效并防止浪费。有关详细信息,请参阅《biofiles》中的文章《替代能源研究用酶》

應用

黑曲霉来源果胶酶可用于:
  • 原生质体释放
  • 原生质体酶混合物,进行酶解
  • 糖的部分糖化
  • 研究其在植物病原菌入侵植物组织、农产品变质、各种食品加工和植物生物技术应用中的作用

用于植物原生质体制备,在细胞器分离前消化细胞壁。

生化/生理作用

黑曲霉中选定菌株生成的果胶酶制剂:主要含有果胶转移酶、多聚半乳糖醛酸酶和果胶酯酶以及少量的半纤维素酶和纤维素酶。果胶酶水解果胶,果胶是细胞壁的一个组成部分。它们可能攻击甲基酯化果胶或去酯化果胶。它是果胶酶活性的来源,还含有纤维素酶和半纤维素酶活性。果胶酶催化果胶和其他半乳糖醛酸中的a-(1-4)-Dgalactosiduronic键的随机水解。

單位定義

在25°C条件下,当pH为4.0时,一个单位每分钟将释放从多聚半乳糖醛酸中得到的1.0 μ摩尔的半乳糖醛酸。

If two related plant species hybridize, their genomes may be combined and duplicated within a single nucleus, thereby forming an allotetraploid. How the emerging plant balances two co-evolved genomes is still a matter of ongoing research. Here, we focus on

Good preparations are essential for informative analysis of both somatic and meiotic chromosomes, cytogenetics, and cell divisions. Fluorescent chromosome staining allows even small chromosomes to be visualized and counted, showing their morphology. Aneuploidies and polyploidies can be established for species

Structural chromosome rearrangements involving translocations, fusions and fissions lead to evolutionary variation between species and potentially reproductive isolation and variation in gene expression. While the wheats (Triticeae, Poaceae) and oats (Aveneae) all maintain a basic chromosome number of x=7, genomes
