Salmonella utilizes L-arabinose to silence virulence gene expression for accelerated pathogen growth within the host [PDF]

Gut Microbes
Carbon source is an important nutrient for bacteria to sustain growth and often acts as a signal that modulates virulence expression. L-arabinose is produced by plants and plays an important role in regulating the global gene expression of bacteria ...

GalR, GalX and AraR co‐regulate d‐galactose and l‐arabinose utilization in Aspergillus nidulans [PDF]

Microbial Biotechnology, 2022
Summary Filamentous fungi produce a wide variety of enzymes in order to efficiently degrade plant cell wall polysaccharides. The production of these enzymes is controlled by transcriptional regulators, which also control the catabolic pathways that ...

L-Arabinose Elicits Gut-Derived Hydrogen Production and Ameliorates Metabolic Syndrome in C57BL/6J Mice on High-Fat-Diet. [PDF]

Nutrients, 2019
Obesity and metabolic syndrome (MS) associated with excess calorie intake has become a great public health concern worldwide. L-arabinose, a naturally occurring plant pentose, has a promising future as a novel food ingredient with benefits in MS; yet the

Metabolic Engineering for Improved Fermentation of L-Arabinose.

Journal of Microbiology and Biotechnology, 2019
L-Arabinose, a five carbon sugar, has not been considered as an important bioresource because most studies have focused on D-xylose, another type of five-carbon sugar that is prevalent as a monomeric structure of hemicellulose.

Induction by Bradyrhizobium diazoefficiens of Different Pathways for Growth in D-mannitol or L-arabinose Leading to Pronounced Differences in CO2 Fixation, O2 Consumption, and Lateral-Flagellum Production

Frontiers in Microbiology, 2018
Bradyrhizobium diazoefficiens, a soybean N2-fixing symbiont, constitutes the basic input in one of the most prominent inoculant industries worldwide. This bacterium may be cultured with D-mannitol or L-arabinose as carbon-plus-energy source (C-source ...

Effects of L-arabinose by hypoglycemic and modulating gut microbiome in a high-fat diet- and streptozotocin-induced mouse model of type 2 diabetes mellitus.

Journal of food biochemistry, 2021
L-arabinose is a good and healthy food additive. This study was conducted to investigate the effect of L-arabinose in a mouse model of type 2 diabetes mellitus (T2DM) induced by exposure to a high-fat diet (HFD) and streptozotocin (STZ).

L-Arabinose 1-dehydrogenase: A novel enzyme involving in bacterial L-arabinose metabolism [PDF]

Nucleic Acids Symposium Series, 2005
Azospirillum brasiliense converts L-arabinose to alpha-ketoglutarate via five hypothetical enzymatic steps. We purified and characterized L-arabinose 1-dehydrogenase (EC 1.1.1.46) catalyzing conversion of L-arabinose to L-arabino-gamma-lactone as an enzyme involved in the first step of this L-arabinose metabolic pathway.

L-arabinose metabolism in Herbaspirillum seropedicae [PDF]

Journal of Bacteriology, 1989
The pathway for L-arabinose metabolism in Herbaspirillum seropedicae was shown to involve nonphosphorylated intermediates and to produce alpha-ketoglutarate. The activities of the enzymes and the natures of several intermediates were determined.

Identification of an l-Arabinose Reductase Gene in Aspergillus niger and Its Role in l-Arabinose Catabolism [PDF]

Journal of Biological Chemistry, 2010
The first enzyme in the pathway for l-arabinose catabolism in eukaryotic microorganisms is a reductase, reducing l-arabinose to l-arabitol. The enzymes catalyzing this reduction are in general nonspecific and would also reduce d-xylose to xylitol, the first step in eukaryotic d-xylose catabolism.

L-arabinose metabolism in Azospirillum brasiliense [PDF]

Journal of Bacteriology, 1982
An oxidative pathway by which L-arabinose is converted to alpha-ketoglutarate in crude extracts of Azospirillum brasiliense is demonstrated. Specific activities of enzymes involved in the pathway were determined, and several pathway intermediates were identified.
