Abstract
- A transglucosylase fraction has been obtained from the mycelium of Aspergillus niger. 2. The preparation will transfer alpha-d-glucopyranosyl residues from maltose and other alpha-d-glucopyranosides to phenolic and alcoholic hydroxyl groups and to carboxylic acid groups. 3. alpha-Isomaltosides and alpha-maltosides are formed when resorcinol and catechol are used as acceptors. 4. pH precipitation and DEAE-cellulose chromatography were used to resolve the activity into two fractions. The properties, in particular polyol inhibition, of one of these fractions have been examined in detail.
摘要
- 已从黑曲霉的菌丝体中获得一种转葡糖基酶组分。2. 该制剂会将α-D-吡喃葡糖基残基从麦芽糖和其他α-D-吡喃糖苷转移至酚羟基、醇羟基和羧酸基团。3. 当间苯二酚和邻苯二酚用作受体时，会形成α-异麦芽糖苷和α-麦芽糖苷。4. 采用pH沉淀和DEAE-纤维素色谱法将该活性分离成两个组分。已对其中一个组分的性质，尤其是多元醇抑制作用进行了详细研究。
