應用

异淀粉酶(来源于假单胞菌属)已用于淀粉脱支以及链长分布测定。

生化/生理作用

Pseudomonas amyloderamosa是异淀粉酶的常用生产菌种。在表面活性剂的存在下,异淀粉酶可用于生产一系列麦芽寡糖。异淀粉酶可在琼脂糖、纤维素和生玉米淀粉组成的多糖基质上固化。

To determine the type and frequency of pancreatic lesions detected by magnetic resonance cholangiopancreatography (MRCP) in subjects with asymptomatic pancreatic hyperenzymemia and to assess for a possible relationship between these lesions and the hyperenzymemia. From January 2005 to May 2008

Several studies have suggested that debranching enzymes (DBEs) are involved in the biosynthesis of amylopectin, the major constituent of starch granules. Our systematic analysis of all DBE mutants of Arabidopsis thaliana demonstrates that when any DBE activity remains, starch granules

Glycogen, highly branched (1-->4)(1-->6)-linked alpha-d-glucan, can be extracted from natural sources such as animal tissues or shellfish (natural source glycogen, NSG). Glycogen can also be synthesized in vitro from glucose-1-phosphate using the cooperative action of alpha-glucan phosphorylase (GP, EC 2.4.1.1)

Starch debranching is fundamental for understanding the structure-function relationships of starch. In this paper, atomic force microscopy (AFM) was used to investigate potato starch by isoamylase [EC 3.2.1.68] debranching at nanometer scale. The hydrolysates were separated by gel-permeation chromatography and
