普鲁兰酶生物活性

[ 描述 ]:

普鲁兰酶(R-酶)是一种淀粉脱支酶,常用于生化研究。普鲁兰酶水解淀粉、支链淀粉、普鲁兰和相关寡糖中的α-1,6葡萄糖苷键。普鲁兰酶在糖化过程中将多糖转化为小的发酵糖[1]。

Gene cloning and enzymatic characterization of alkali-tolerant type I pullulanase from Exiguobacterium acetylicum.

Lett. Appl. Microbiol. 60(1) , 52-9, (2015)

A pullulanase gene (Pul3YH5) of 2568 bp, which encodes a protein containing 855 amino acid residues, was cloned from the alkaliphilic bacterium Exiguobacterium acetylicum YH5. The pullulanase (Pul3YH5...

Carrier free co-immobilization of alpha amylase, glucoamylase and pullulanase as combined cross-linked enzyme aggregates (combi-CLEAs): a tri-enzyme biocatalyst with one pot starch hydrolytic activity.

Bioresour. Technol. 147 , 269-75, (2013)

A tri-enzyme biocatalyst "combi-CLEAs" with starch hydrolytic activity was prepared from commercially available alpha amylase, glucoamylase and pullulanase preparations by aggregating enzymes with amm...

Properties of retrograded and acetylated starch produced via starch extrusion or starch hydrolysis with pullulanase.

Carbohydr. Polym. 97(2) , 551-7, (2013)

The aim of the present study was to determine the impact of serial modifications of starch, including firstly starch extrusion or hydrolysis with pullulanase, followed by retrogradation (through freez...
