IDENTIFICATION OF THE ROLE OF [METHYL]GLUCURONIC ACID ON ARABINOGALACTAN POLYSACCHARIDES IN ARABIDOPSIS THALIANA
… study knock-out Arabidopsis thaliana plants of glycosyltransferases that transfer sugars specifically onto AG-polysaccharides. Glucuronic acid makes up about 10% of the arabinogalactan polysaccharide structure in Arabidopsis thaliana cell culture AGPs. Previously, the glucuronic acid transferase …

Membrane protein conformational dynamics and ligand-binding interactions in bacterial glycoconjugate biosynthesis
… such as those responsible for bacterial glycosylation, remain challenging to structurally characterize at all. Bacterial glycan synthesis pathways are essential for cell function yet highly variable between strains, making them promising systems for targeted antibiotic development. Many …

A Search for the Counter-Immune Mechanisms of Mycobacterium Tuberculosis
… of a putative glutamine transporter, Rv2958c - a glycosyl-transferase, and pstA1/Rv0930 - a membrane spanning domain of an inorganic phosphate transporter. Monotypic IV infections confirmed that these mutants replicate freely in the tissues of IFN-γ-/- mice and kill these mice with similar …

Lipopolysaccharide, K antigen, and other components of the bacterial cell surface important for S. meliloti-alfalfa symbiosis
… the lpsB389 mutant, which codes for a predicted glycosyl transferase involved with LPS core synthesis. Bacteria carrying the lpsB389 mutation are capable of carrying out the first steps of nodule invasion on alfalfa plants. However, they display dramatic abnormalities upon entry into plant cells. …

Studies of the Class A High-Molecular Weight Penicillin-Binding Proteins in Bacillus subtilis
… transpeptidase activity and the glycosyl transferase (GT) activity required for the polymerization of the glycan strands. The Class A PBPs in Bacillus subtilis are PBP1, PBP4, PBP2c, and PBP2d (YwheE) and they are encoded by ponA, pbpD, pbpF, and pbpG (ywhE), respectively. These …

Small Molecule Regulator of ENTPD5, and ER Enzyme in the PTEN/AKT Pathway
… UDPase that hydrolyzes UDP, the by-product of glycosyl-transferase, into UMP. Only in its monophosphate form can Uridine nucleotide exits ER through an antiporter by exchanging a molecule of UDP-sugar from cytosol. Up-regulation of ENTPD5 in PTEN-null MEF cells accelerates glycosylation …

Identification and characterization of a novel capsule-like complex surface antigen of Francisella tularensis
… be significantly diminished by deleting two glycosyl transferase genes (LVSΔ1423-22) in the putative polysaccharide locus, FTL_1432-FTL_1421. In addition, I determined that the CLC was not a typical polysaccharide capsule, but was in fact composed of over 50 proteins and glycoproteins …

Identification of Quorum Sensing Genes in Halococcus Hamelinensis SP. Nov. 100Na1
… were similar. One of those annotations was a glycosyl transferase which was recently found to be important for polysaccharide production and might be quorum sensing-regulated as Hcc. hamelinensis produces EPS towards the stationary phase during the development of biofilms. An annotation for a …

Strukturelle und mechanistische Arbeiten an Triterpen-Cyclasen aus Alicyclobacillus acidocaldarius und Arabidopsis thaliana sowie Kristallstrukturen der katalytischen Fragmente von AB-Toxinen aus Clostridium difficile und Bacillus sphaericus
… die charakteristische alpha/beta-Faltung der Glycosyltransferasen des GT-A-Typs auf und enthält das aktive Zentrum. Unter Berücksichtigung von Strukturvergleichen und biochemischen Daten wurde ein Katalysemechanismus vorgeschlagen. Zudem konnte die unterschiedliche Kosubstratspezifität der …
