High-yield enzymatic bioconversion of hydroquinone to α-arbutin, a powerful skin lightening agent, by amylosucrase
Abstractα-Arbutin (α-Ab) is a powerful skin whitening agent that blocks epidermal melanin biosynthesis by inhibiting the enzymatic oxidation of tyrosine and l-3,4-dihydroxyphenylalanine (l-DOPA).Expand

Isomaltulose production via yeast surface display of sucrose isomerase from Enterobacter sp. FMB-1 on Saccharomyces cerevisiae.
The gene encoding sucrose isomerase from Enterobacter sp. FMB-1 species (ESI) was displayed on the cell surface of Saccharomyces cerevisiae EBY100 using a glycosylphosphatidylinositol (GPI) anchorExpand

Microbial production of palatinose through extracellular expression of a sucrose isomerase from Enterobacter sp. FMB-1 in Lactococcus lactis MG1363.
Sucrose isomerase (SIase) has been used to produce palatinose, a structural isomer of sucrose, which has many beneficial health properties, such as low-glycemic and low-insulinemic indices. A geneExpand

Enzymatic synthesis of salicin glycosides through transglycosylation catalyzed by amylosucrases from Deinococcus geothermalis and Neisseria polysaccharea.
Amylosucrase (ASase, EC 2.4.1.4) is a member of family 13 of the glycoside hydrolases that catalyze the synthesis of an alpha-(1-->4)-linked glucan polymer from sucrose instead of an expensiveExpand

Molecular Cloning of the Amylosucrase Gene from a Moderate Thermophilic Bacterium Deinococcus Geothermalis and Analysis of its Dual Enzyme Activity
Abstract Amylosucrase (AS; EC 2.4.1.4) is an interesting enzyme to form an insoluble amylosetype polymer from sucrose. A putative AS gene was cloned from Deinococcus geothermalis (dgas) andExpand

Highly selective biotransformation of arbutin to arbutin-α-glucoside using amylosucrase from Deinococcus geothermalis DSM 11300
Abstract Arbutin (Ab, 4-hydroxyphenyl β-glucopyranoside) is a glycosylated hydroquinone known to prevent the formation of melanin by inhibiting tyrosinase. An arbutin-α-glucoside was synthesized byExpand

Functional expression of amylosucrase, a glucan-synthesizing enzyme, from Arthrobacter chlorophenolicus A6.
A gene (acas) designated as alpha-amylase was cloned from Arthrobacter chlorophenolicus A6. The multiple amino acid sequence analysis and functional expression of acas revealed that this gene reallyExpand

Improved 1,3-propanediol production by Escherichia coli from glycerol due to Co-expression of glycerol dehydratase reactivation factors and succinate addition
Escherichia coli was engineered to produce 1,3-propanediol (1,3-PDO) from glycerol, an inexpensive carbon source. This was done by introducing a synthetic pathway consisting of glycerol dehydratase,Expand

Molecular Cloning and Functional Expression of a New Amylosucrase from Alteromonas macleodii
The presence of amylosucrase in 12 Alteromonas and Pseudoalteromonas strains was examined. Two Alteromonas species (Alteromonas addita KCTC 12195 and Alteromonas macleodii KCTC 2957) possessed genesExpand

One-pot bioconversion of sucrose to trehalose using enzymatic sequential reactions in combined cross-linked enzyme aggregates.
Amylosucrase (AS), maltooligosyltrehalose synthase (MTS), and maltooligosyltrehalose trehalohydrolase (MTH) were used in combined cross-linked enzyme aggregates (combi-CLEAs) to achieve one-stepExpand
