Identification and functional characterization of cDNAs coding for hydroxybenzoate/hydroxycinnamate glucosyltransferases co-expressed with genes related to proanthocyanidin biosynthesis

, 2011
International audienceGrape proanthocyanidins (PAs) play a major role in the organoleptic properties of wine. They are accumulated mainly in grape skin and seeds during the early stages of berry development.

Purification and properties of glucosyltransferase fromAureobasidium

Journal of Industrial Microbiology, 1994
Purification and properties of glucosyltransferase, which produces panose (Glc alpha 1-->6Glc alpha 1-->4Glc) and isomaltose (Glc alpha 1-->6Glc) from maltose (Glc alpha 1-->4Glc), are reported. The enzyme, from Aureobasidium, was purified to homogeneity by fractionations involving ammonium sulfate and DEAE-Cellulofine, S-Sepharose Fast Flow and ...

Research Progress of Glucansucrase from Lactic Acid Bacteria

Shipin gongye ke-ji
Glucansucrase (EC.2.4.5.1) is a class of α-glucosyltransferases, mainly produced by lactic acid bacteria such as Leuconostoc, Streptococcus and Lactobacillus. The structure and catalytic mechanism of glucansucrase are diverse, and it is an important tool

Structural Analysis of the Functional Influence of the Surface Peptide Gtf-P1 on Streptococcus Mutans Glucosyltransferase C Activity

, 2009
Glucosyltransferases (GtfB/C/D) in Streptococcus mutans are responsible for synthesizing water-insoluble and water- soluble glucans from sucrose and play very crucial roles in the formation of dental plaque. A monoclonal antibody against a 19-mer peptide

Characterization of sophorolipid biosynthetic enzymes from Starmerella bombicola

, 2015
Altering glycolipid structure by genetic engineering of Starmerella bombicola is a recently started research topic and worthy alternative to the unsuccessful selective feeding strategies conventionally applied to reach this goal.

Reactive Oxygen Species as Additional Determinants for Cytotoxicity of Clostridium difficile Toxins A and B

Toxins, 2016
Clostridium difficile infections can induce mild to severe diarrhoea and the often associated characteristic pseudomembranous colitis. Two protein toxins, the large glucosyltransferases TcdA and TcdB, are the main pathogenicity factors that can induce ...
