amylosucrase is a transglucosidase that catalyses the synthesis of an amylose-type polymer from sucrose, an abundant agro-resource |
| 2.4.1.4 | more |
the enzyme catalyzes the synthesis of a water-insoluble amylose-like polymer from sucrose, a readily available and low-cost agroresource |
| 2.4.1.4 | more |
the enzyme catalyze the synthesis of an alpha-(1,4)-linked glucan polymer from sucrose instead of an expensive activated sugar, such as ADP- or UDP-glucose |
| 2.4.1.4 | more |
amylosucrase (AS), a glucosyltransferase from Neiserria polysaccharea, produces an insoluble alpha-1,4-linked glucan polymer by consuming sucrose and releasing fructose. This reaction does not require a-D-glucosyl-nucleotide-diphosphate like ADP- or UDP-glucose, but rather uses the energy generated by splitting sucrose in order to synthesise the glucan polymer |

amylosucrase from Neisseria polysaccharea is a transglucosylase that synthesizes an insoluble amylose-like polymer from sole substrate sucrose, product isolation and analysis, overview |
| 2.4.1.4 | more |
amylosucrase is a versatile enzyme that carries out 3 different catalytic reactions: 1. hydrolysis of sucrose to release a glucose molecule and a fructose molecule, 2. synthesis of glucose polymers from liberated glucose molecules, and 3. production of the sucrose isomers turanose and isomaltulose through an isomerization reaction. In addition, the enzyme can attach glucose molecules to an atypical substrate, thereby generating unnatural glucan-conjugates. The enzyme produces glucose, fructose, soluble maltooligosaccharide, insoluble glucan, and sucrose isomers (turanose and trehalulose) using only sucrose as a substrate |

amylosucrase synthesizes alpha-1,4-glucans using sucrose as a sole substrate |
| 2.4.1.4 | more |
the amylosucrase from Neisseria polysaccharea naturally catalyzes the synthesis of alpha-glucans from the widely available donor sucrose. NpAS is highly specific for its natural substrate and subsite -1 (according to GH nomenclature) plays a major role in the recognition of the sucrose glucosyl moiety through a highly efficient hydrogen bonding interaction network, subsite 21 is responsible for the high affinity for sucrose |
| 2.4.1.4 | more |
the enzyme AMS exhibits multiple catalytic activities. Primarily, it can hydrolyze sucrose to glucose and fructose or transfer glucose from sucrose hydrolysis to another glucose or acceptormolecule. As a side reaction, it is also able to catalyze the isomerization of sucrose to turanose or trehalulose |

treatment of pre-gelatinized rice and barley starches with amylosucrase from Neisseria polysaccharea for resistant starch production. Analysis of reaction efficiency, resistant starch content, amylopectin branch-chain length distribution, solubility, welling power, pasting viscosity, and thermal transition properties, detailed overview |
