Cell wall proteins (CWPs) with enzymatic activity on cell wall polysaccharides, have been studied widely. Another investigations take place in the study of N-glycosylations of CWPs and enzymes with activity on glycosidic linkages. alpha-mannosidase (alpha-Man; EC 3.2.1.24) and beta-d-N-...
α-Amylases (1,4-α-d-glucan-glucanohydrolase, EC 3.2.1.1) are endoglucanases that catalyze the hydrolysis of the α-1,4-glycosidic linkages in starch and related polysaccharides such as amylose, amylopectin, and glycogen. From: Coffee in Health and Disease Prevention, 2015 ...
MA is classified as an exo-hydrolase that cleaves α-1,4 glucosidic bonds in polysaccharides successively, removing maltose residues from the non-reducing ends of the chains (Keeratiburana et al., 2020a;Zhong, Keeratiburana, et al., 2021). Additionally, MA shows a high transglycosylation a...
Daqu is the most important fermentation starter for Chinese liquor, with large number of microbes and enzymes being openly enriched in the Daqu system over thousands of years. However, only a few enzymes have been analyzed with crude protein for total li
Specificity:endo-hydrolysis of (1,4)-α-D-glucosidic linkages in polysaccharides containing three or more (1,4)-α-linked D-glucose units. Specific Activity:~ 50 U/mg (40oC, pH 6.5 on Ceralpha Reagent) Unit Definition:One Unit of α-amylase is the amount of enzyme required to release...
BACKGROUND: alpha-Amylases constitute a family of enzymes that catalyze the hydrolysis of alpha-D-(1,4)-glucan linkages in starch and related polysaccharides. The Amaranth alpha-amylase inhibitor (AAI) specifically inhibits alpha-amylases from insects, but not from mammalian sources. AAI is the ...
(Hashim, 2019;Park et al., 2017;Samanta, 2020;Singh, Singh and Sachan, 2019a). The development of formulations containing enzymes,emulsifiers, oligosaccharides, andpolysaccharideshas been used to decrease the rate of retrogradation and to delay staling of starchy products (Park et al., 2017)...
Digestion: Alpha-amylase (EC3.2.1.1), both from salivary gland and pancreas, cleaves [1>4] Glc bonds in starch, glycogen, and similar polysaccharides and oligosaccharides. Amylose is not well digestible unless cooked, steeped, or thoroughly chewed and wetted because otherwise, the starch granules...
Carrageenan is a linear polysaccharide having repeating galactose units and 3,6 anhydrogalactose units, both of which can be sulfated or nonsulfated, joined by alternating 1-3 and beta 1-4 glycosidic linkages. Carrageenan is a hydrocolloid which is heat extracted from several species of red seawee...
α-Amylases hydrolyze starch, glycogen, and related polysaccharides by cleaving internal α-1,4-glucosidic bonds at random. α-Amylases, particularly from Bacilli, have been used for a variety of different purposes, including starch liquefaction and saccharification, textile desizing, starch modificati...
