α-淀粉酶能水解淀粉中的α-1,4-葡萄糖苷键。能将淀粉切断成长短不一的短链糊精和少量的低分子糖类,从而使淀粉糊的黏度迅速下降,即起到降低稠度和“液化”的作用,所以此类淀粉酶又称为液化酶。

The CELLG3 assay reagent for the measurement of endo-cellulase (endo-1,4-β-glucanase) contains two components;

1) 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-D-cellotrioside (BCNPG3) and 2) thermostable β-glucosidase. The benzylidene blocking group prevents any hydrolytic action by the β-glucosidase on BCNPG3.  Incubation with an endo-cellulase generates a non-blocked colourimetric oligosaccharide that is rapidly hydrolysed by the ancillary β-glucosidase.  The rate of formation of 2-chloro-4-nitrophenol is therefore directly related to the hydrolysis of BCNPG3 by the endo-cellulase.  The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH 9.0).
Please note that a new assay kit (K-CELLG5) is now available for the measurement of endo-cellulase.  The CELLG5 reagent contains a cellopentaose core and exhibits vastly improved sensitivity for some cellulases.  In addition, the exchange of the benzylidene blocking group in CELLG3 for 3-keto-butylidene in CELLG5 improves the substrate’s water solubility significantly, allowing for a reduction in the concentration of DMSO required in the assay.  As DMSO is known to inhibit certain cellulases, this is another benefit in using CELLG5.  Megazyme now recommends the use of K-CELLG5 for all assays for the measurement of endo-cellulase.
