Application
Pullulanase is a glucanase that degrades pullulan. It is commonly used for starch-debranching as well as to study polysaccharide utilization[1].
Biochem/physiol Actions
Type I pullulanases specifically hydrolyse α-1,6 linkages, while type II pullulanases are also able to hydrolyse α-1,4 linkages.

What is the meaning of NPUN/g of pullulanase enzyme E2412?
1 risposta-
The activity is expressed as NPUN/g, which refers to New Pullulanase Unit Novozymes (NPUN) per milligram of protein. The international unit correspondence is described as follows: 1 NPUN = 0.35 PUN (Pullulanase Unit Novozymes), where 1 PUN is defined as the amount of enzyme that, under standard conditions, releases 1 ?mol of glucose per minute.

I was wondering the proportion of type 1 and type2 in pullulanase?
1 risposta-
Product Code E2412 contains both Pullulanase 1 and 2, but the exact ratio is considered proprietary.

May I know how to make 10units/mL sample from the bottle?
1 risposta-
The activity in the batch-specific Certificate of Analysis is expressed as NPUN/g. The international unit correspondence is described as follows: 1 NPUN = 0.35 PUN, where 1 PUN is defined as the amount of enzyme that releases 1 μmol of glucose per minute under standard conditions.
The Certificate of Analysis also reports the density (g/mL) of the product. To calculate the activity in units per milliliter (UPUN/mL), multiply the activity (NPUN/g) by the density (g/mL). Further dilution can then be performed to achieve the desired final concentration.

I was wondering if product E2412-50ML is a type 1 or type 2 pullulanase (degrades alpha1,6 linkages only or both alpha1,4 and 1,6?)
1 risposta-
E2412 contains both Type 1 and Type 2 Pullulanases.

What is the molecular weight of this Pullulanase enzyme? And is there any glucose in the enzyme solution?
1 risposta-
The molecular weight has not been determined, however, a search of the literature indicates that the general molecular weight of Pullulanase, CAS 9075-68-7, ranges from 70 - 115 kDa. This is a product of Novozymes Corp. The manufacturer considers the formulation of this product proprietary but has noted that this material is pure Oligo-1,6-Glucosidase.
