Blood group antigens of the H, ABO, Lewis, and historical “P” blood groups are defined by small carbohydrate epitopes expressed as posttranslational modifications on glycoproteins, mucins, and glycolipids. Their synthesis is complex and dependent on several distinct glycosyltransferases and interrelated biosynthetic pathways. In many cases, carbohydrate antigens share features of more than one ...
Clostridium difficile is the principal cause of nosocomial infectious diarrhea worldwide. The pathogen modifies its flagellin with either a type A or type B O-linked glycosylation system, which has a contributory role in pathogenesis. We study the functional role of glycosyltransferases modifying type B flagellin in the 023 and 027 hypervirulent C. difficile lineages by mutagenesis of five puta...
The Rhizobium etli CE3 O antigen is a fixed-length heteropolymer. The genetic regions required for its synthesis have been identified, and the nucleotide sequences are known. The structure of the O antigen has been determined, but the roles of specific genes in synthesizing this structure are relatively unclear. Within the known O-antigen genetic clusters of this strain, nine open reading frame...
This review describes and discusses the structure, biosynthesis applications of exopolysaccharides from lactic acid bacteria. These substances are classified as homopolysaccharides, which synthesised sucrose through action extracellular glycosyltransferases or heteropolysaccharides, repeating unit precursors formed in cytoplasm assembled extracellularly by sequential addition nucleotide sugars....
Cyclodextrin glycosyltransferase (CGTase) is a multifunctional enzyme that hydrolyzes the <em>α</em>-glycosidic bond between two sugar molecules and synthesizes cyclodextrins (CDs) other transglycosylation products. It ubiquitously present extracellular offers CGTase-producing organism sole right onto starch substrates over microbes. The review provides brief account of diversity am...
Genome-Wide Analysis and Functional Characterization of the UDP-Glycosyltransferase Family in Grapes
Grape (Vitis vinifera) produces a variety of secondary metabolites, which can enhance nutrients and flavor in fruit wine. Uridine diphosphate-glycosyltransferases (UGTs) are primarily responsible for the availability metabolites by glycosylation modification. Here, total 228 putative UGTs were identified V. vinifera, VvUGTs clustered into 15 groups (A to O) unevenly distributed on 18 chromosome...
