产品描述

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in cellulosic ethanol research. For more information see the article in biofiles.

β-Glucosidase from almonds belongs to the family 1 of the glycoside hydrolases. Almonds contain prunasin hydrolases (PH) and amygdalin hydrolase. Nine types of PHs are associated with almonds. PHs have signal peptide sequence and correspond to molecular weight in the range 50 to 75 kDa. PHs also have ITENG, NEP and INKKGIEYY motifs conserved and have N-glycosylation sites.

Application

β-Glucosidase from almonds has been used:
•  in enzyme inhibition studies by 1,5-dideoxy-1,5-imino-d-xylitol(DIX) derivates
• as a control in for comparison of soybean isofavone glycosides degradation by β-Glucosidase from Talaromyce leycettanus
• as a medium component during saccharification and fermentation of yeast

β-葡萄糖苷酶还可用于合成葡萄糖苷和岩藻糖苷(在制药、化妆品和洗涤剂行业具有多种潜在的应用)、从类黄酮和异黄酮糖苷中水解除去糖苷配基部分、增强果汁和葡萄酒的风味、以及寡糖的生物合成

包装

Biochem/physiol Actions

Prunasin hydrolase (PH) is a β-glucosidase that degrades prunasin to mandelonitrile and glucose. Amygdalin hydrolase hydrolyzes amygdalin to prunasin and glucose. β-Glucosidase is mesostable and is sensitive to temperature at 60 °C and above. It is highly sensitive to high pressure.

β-葡萄糖苷酶可参与β-D-糖苷中连接碳水化合物残基的β-糖苷键的水解。它们可将内切和外切葡聚糖酶产生的纤维二糖和纤维寡糖转化为葡萄糖。
