L-arabinose metabolism in Azospirillum brasiliense [PDF]
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.

Development of a selection system for the detection of L-ribose isomerase expressing mutants of Escherichia coli [PDF]
L-Arabinose isomerase (E.C. 5.3.1.14) catalyzes the reversible isomerization between L-arabinose and L-ribulose and is highly selective towards L-arabinose.

Sustainable Synthesis of Chiral Tetrahydrofurans through the Selective Dehydration of Pentoses [PDF]
L-Arabinose is an abundant resource available as a waste product of the sugar beet industry. Through use of a hydrazone-based strategy, L-arabinose was selectively dehydrated to form a chiral tetrahydrofuran on a multi-gram scale without the need for ...

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