Investigating galactose metabolism in Streptococcus pneumoniae
… airway sterility. In the absence of glucose, galactose is the predominant sugar in this niche. Galactose can be metabolised by two pathways in the pneumococcus, the Leloir pathway and the tagatose-6-phosphate pathway. A study by Trappetti et al., in 2017 was the first to show a link between …

Structural Studies of Catalysis and Processing in Galactose
The fungal copper containing enzyme galactose oxidase is one of the earliest examples of a protein derived radical cofactor. A covalent bond, formed between the active site cysteine and the Cc of a tyrosine act as a site for radical formation, allowing the enzyme to catalyse the two electron …

Characterization of an ethanologenic yeast inhibiting atypical galactose metabolism
… amounts of the recalcitrant hexose sugar galactose. The consumption of galactose in hexose sugar-fermenting yeasts is often delayed with respect to other sugars, such as glucose and mannose, because of an intrinsic preference for carbon sources requiring less energy in the preparatory …

Fluorescence photophysics, characterisation and application of labelled glucose/galactose binding protein
There is currently a pressing need for reliable, minimally-invasive, continuous glucose monitoring for the treatment of diabetes mellitus. One promising glucose sensor is bacterially-derived glucose binding protein (GBP). In this project, the modified triple mutant H152C/A213R/L238S-GBP (mGBP) was …

Rat Lymphocyte Surface Glycoproteins Mediating Mitogenesis by Periodate or Neuraminidase Plus Galactose Oxidase
… agents periodate and neuraminidase plus galactose oxidase (NGO). Lymph node cell blastogenesis induced by these oxidative agents was inhibited by reduction with borohydride or reaction with cysteine methyl ester (CME) without affecting the ability of lymph node cells (LNC) to respond to …

Investigating the role of the UDP-galactose transporter SLC35A2 in the regulation of HIF signalling
… of HIF is of intense interest. The Golgi UDP-galactose transporter SLC35A2 was identified by the Ashcroft group as a novel regulator of HIF-α, and CHO cells that had lost SLC35A2 exhibited elevated HIF-α protein in normoxia. It is known that the absence of SLC35A2 in the Golgi leads to …

Molecular characterisation of XvVTC2, a gene coding for a GDP-L-galactose phosphorylase from Xerophyta viscosa
Climate change is predicted to have a negative impact on world food security in the next 40 years. Resurrection plants can withstand highly variable and harsh climatic conditions. This makes them ideal candidates to elucidate possible mechanisms which can be used to adapt crop plants to tolerate …

Bioreaction and separation in preparative batch chromatographic columns : the hydrology of lactose to yield glucose,galactose and oligosaccharides
The initial aim of this project was to improve the performance of a chromatographic bioreactor-separator (CBRS). In such a system, a dilute enzyme solution is pumped continuously through a preparative chromatographic column, while pulses of substrate are periodically injected on to the column. …

Avaliação das interações biológicas por eletroquímica entre bactérias endofíticas e lectina galactose específica (BmoLL) isolados de folhas de Bauhinia monandra Kurz
… entre bactérias endofíticas e a lectina galactose específica BmoLL isoladas de folhas de B. monandra com técnicas de aglutinação e eletroquímica como estratégia de caracterização da lectina. Nos ensaios de aglutinação BmoLL foi testada para três estírpes bacterianas Bacillus sp., …

Protective effects of regular exercise and Korea red ginseng against high-fat diet-increased renal injury in ᴅ-galactose-induced aging rats
… to investigate whether HFD would accelerate ᴅ-galactose (GAL)-induced renal injury and to examine the preventive effects of a regular exercise and KRG on GAL/HFD -induced renal injury. In the first experiment, age-related renal injury was induced by an administration with GAL (100 mg/kg, i.p.) …

Base editing of Galactose-1-Phosphate Uridylyl Transferase as a novel gene therapy approach to treat Q188R mutation in a cellular model of Classic Galactosemia
Classic Galactosemia (CG) is a rare genetic disorder represented by the inability to convert galactose to glucose. A mutation at the galactose-1-phosphate uridylyltransferase (GALT) enzyme coding gene halts galactose metabolism which leads to the accumulation of galactose-1-phosphate and …

Correlated evolution in experimental populations of yeast
… growth rate increased and yield decreased in a galactose-limited environment, in both haploid and diploid lines. I demonstrate that this trade-off between rate and yield in the galactose environment results from an ecological feedback between these life-history traits in batch cultures rather …

Gold Nanoparticles as a Delivery System of Oligonucleotides into the Brain
… covalently coated with glucose, OEG-amine/galactose or OEG-amine/galactose/insulin. The two formulations with OEG-amine showed higher uptake efficiency into both human brain endothelial cells (hCMEC/D3) and primary astrocytes, as determined by electron microscopy. Nanoparticles located in …

Electronic and solvent effects on monosaccharide conformations
… preferences of the monosaccharides glucose and galactose are different from each other and non-intuitive (from a steric point of view) in their preferences for gauche conformers. These molecules exhibit very different biological and thermodynamic properties in, for example their binding to …
