极限糊精

大麦极限糊精酶（LD，EC3.2.1.41）是麦芽中淀粉水解的重要酶类之一，主要负责催化支链淀粉和极限糊精内部的-α1,6-D糖苷键；

The starch debranching enzyme limit dextrin ase ( LD , EC 3.2.1.41 ) is one of the key enzymes in malting , which catalyses the hydrolysis of α - 1,6-D-glucosidic bonds in amylopectin and limit dextrin .

浸泡对淀粉酶活性有抑制作用，一般与未浸泡小麦种子相比，浸泡24h后小麦α-淀粉酶、β-淀粉酶和极限糊精酶活性均略有下降；

Steeping the wheat seeds depressed the activity of the carbohydrases , after steeping 24 hours , the activity of α - amylase , β - amylase and limit dextrinase decreased slightly .

The Research Progress and Prospect of Limit Dextrinase

大麦极限糊精酶有自由态、束缚态、潜伏态三种形式。

Barley limit dextrinase ( LD ) has free , latent and bound forms .

潜伏态极限糊精酶活性1-4天逐渐升高，5-7天逐渐下降；

Activity of latent limit dextrinase increases gradually during 1-4 days and decreases gradually during 5-7 days .

束缚态极限糊精酶活性1-3天逐渐升高然后呈下降的趋势.由此推断，发芽大麦中存在三种形式的极限糊精酶的转变过程。

Activity of bound limit dextrinase increases gradually during 1-3 days and then shows a decrease tendency . It can be inferred that transformation of three forms of limit dextrinase exists in the malting barley .
