L-Arabinose inhibits colitis by modulating gut microbiota in mice.

Journal of Agricultural and Food Chemistry, 2019
L-Arabinose is a monosaccharide extracted from plants or fibers, which is known to have a variety of functional properties. In this study, we aim to investigate whether L-Arabinose could inhibit colitis by modulating gut microbiota.

Phosphonate Analogues of Arabinose 5‐Phosphate: Putative Ligands for Arabinose 5‐Phosphate Isomerases

European Journal of Organic Chemistry, 2013
AbstractMetabolically stable arabinose 5‐phosphate analogues possessing phosphate mimetic groups at the 5‐position were synthesized and evaluated by saturation‐transfer‐difference (STD) NMR studies for their ability to interact with arabinose 5‐phosphate isomerase.

Heterodimers Reveal That Two Arabinose Molecules Are Required for the Normal Arabinose Response of AraC

Biochemistry, 2012
AraC protein, which regulates expression of the l-arabinose operon in Escherichia coli, is a dimer whose DNA binding affinity for pairs of DNA half-sites is controlled by arabinose. Here we have addressed the question of whether the arabinose response of AraC requires the binding of one or two molecules of arabinose.

One-Pot Bioconversion of l-Arabinose to l-Ribulose in an Enzymatic Cascade.

Angewandte Chemie, 2019
This work reports the one-pot enzymatic cascade that completely converts l-arabinose to l-ribulose using four reactions catalyzed by pyranose 2-oxidase (P2O), xylose reductase, formate dehydrogenase, and catalase.

An l-arabinose binding protein and arabinose permeation in Escherichia coli

Journal of Molecular Biology, 1969
Abstract A search was made for proteins of the arabinose system which bind arabinose, as it is expected that the permease and possibly the C protein could be identified by arabinose binding. One protein was found and this is most probably part of the arabinose permease. It is inducible, can be removed from cells by osmotic shock and easily purified,

L‐arabinose transport and the L‐arabinose binding protein of escherichia coli

Journal of Supramolecular Structure, 1977
AbstractThe active accumulation of L‐arabinose by arabinose induced cultures of Escherichia coli is mediated by 2 independent transport mechanisms. One, specified by the gene locus araE, is membrane bound and possesses a relatively “low affinity.” The other, specified in part by the genetic locus araF, contains as a functional component the L‐arabinose

Modulated Arabinose Uptake and cAMP Signaling Synergistically Improve Glucose and Arabinose Consumption in Recombinant Yeast

Journal of Agricultural and Food Chemistry, 2023
During the production of ethanol from lignocellulose-derived sugars, recombinant yeasts tend to utilize xylose and arabinose after glucose exhaustion. So far, many glucose-insensitive pentose transporters have been reported to counteract this phenomenon, but few studies have described intracellular factors.

Experimental and Kinetic Study of Arabinose Conversion to Furfural in Renewable Butanone–Water Solvent Mixture Catalyzed by Lewis Acidic Ionic Liquid Catalyst

Industrial & Engineering Chemistry Research, 2019
Arabinose, the second most abundant pentose in lignocellulosic biomass, can be dehydrated to produce a well-known platform chemical named furfural. However, the lowest reactivity of arabinose among the aldopentoses in biomass has hindered its application.

Self-Assembled Hybrid Nanoflowers of Manganese Phosphate and l-Arabinose Isomerase: A Stable and Recyclable Nanobiocatalyst for Equilibrium Level Conversion of d-Galactose to d-Tagatose

, 2018
We report on the synthesis and characterization of a novel hybrid nanoflower of manganese and l-arabinose isomerase and its application in synthesis of d-tagatose, a rare sugar of high commercial value.
