Product instruction:α-L-Arabinofuranosidase, α-L-AF) belongs to sugar The base hydrolyzate family can generate a L-Arabic sugar molecule from a polymer containing a propanogenic glycer with arabinose such as arabinopan, arabant glycans, and arabic semi-lactose. This enzyme has an important role in hemicellulose degradation and the maturity of fruits.
α-L-AF decomposition to nitrophenyl-α-L-araboside is a pair of nitrophenol, and the maximum absorption peak is at 400 nm at 400 nm, by determining 400 nm Changes in the absorbance value can be calculated to be alpha-L-AF activity.
