Bottom‐Up Synthesized Glucan Materials: Opportunities from Applied Biocatalysis
Advanced Materials, Volume 36, Issue 27, July 4, 2024.Linear d‐glucans, simple yet versatile polysaccharides, shape nanostructures crucial for biomaterial development. Shifting from top‐down to bottom‐up synthesis using natural and engineered enzymes provides meticulous control over polymer structures, fostering diversification for macromolecular materials.

ChemBioChem, Volume 25, Issue 10, May 17, 2024.Levansucrases from Gluconobacter oxydans, Vibrio natriegens, Novosphingobium aromaticivorans, and Paraburkholderia graminis were used to catalyze the transfructosylation of phenolic compounds and carbohydrates. The selected phenolic acceptor substrates were successfully glycosylated with up to five fructosyl groups transferred from the sucrose donor ...

Specific method for the purification of Streptococcus mutans dextransucrase [PDF]
Infection and Immunity, 1977 A convenient and rapid method for the purification of Streptococcus mutans dextransucrase is described. Affinity chromatography, on a column containing insoluble dextran purified from a culture of S. mutans 6715-49, gave an almost 300-fold purification, with 76% recovery of enzyme.

Effect of addition of wheat bran hydrolysate on bread properties
Journal of Food Science, Volume 89, Issue 5, Page 2567-2580, May 2024.Abstract Although the addition of bran to bread makes it healthier and more functional, it brings with it some technological problems. One way to eliminate these problems is hydrothermal pretreatment of wheat bran. In this study, five different ratios (10%, 20%, 30%, 50%, and 100%) of hydrolysates from hydrothermal pretreatment of wheat bran (150°C, 30

Chemical synthesis of sucrose analogues and the study of their inhibition of dextransucrase [PDF]
, 1980 Several analogues of sucrose were synthesized and tested as inhibitors of dextransucrase. These compounds were as follows: xylsucrose, (alpha)-D-xylopyranosyl fluoride, 6,6'-dideoxy-6,6'-dibromosucrose, 6,6'-dideoxy-6,6'-dichlorosucrose, 6,6'-dideoxy-6,6'

Studies on Dextransucrase Part VI
Nippon Nōgeikagaku Kaishi, 1967 (1) ショ糖培地に生育させたLeuc. mesenteroidesの菌体を音波処理して調製した無緬胞抽出液を,B2グルコシドに作用するとB2を遊離した.また抽出液をB2イソマルトシドに作用すると,B2イソマルトシドはB2グルコシドを経てB2へ,またB2イソマルトトリオシドに作用すると,B2イソマルトトリオシドはB2イソマルトシド,B2グルコシドを経てB2へ順次分解された.B2にグルコース分子が平均10個,あるいは18個結合したようなB2高級少糖類も徐々に,それぞれグルコース分子の結合数がより少ないB2少糖類へ分解された. (2)硫酸アンモニウム分別塩析法によってB2グルコシル化合物の生成および分解の両活性区分が大別された.
