The fungal pathway for L-arabinose catabolism converts L-arabinose to D-xylulose 5-phosphate in five steps. The intermediates are, in this order: L-arabinitol, L-xylulose, xylitol and D-xylulose. Only some of the genes for the corresponding enzymes were known.

Screening for L-Arabinose Fermenting Yeasts
1996Utilization of pentose sugars (D-xylose and L-arabinose) derived from hemicellulose is essential for the economic conversion of biomass to ethanol. Xylose-fermenting yeasts were discovered in the 1980s, but to date, no yeasts have been found that ferment L-arabinose to ethanol in significant quantities.

Extremophiles, 2013
The pathway of L-arabinose degradation was studied in the haloarchaeon Haloferax volcanii. It is shown that L-arabinose is oxidatively degraded to α-ketoglutarate. During growth on L-arabinose, L-arabinose dehydrogenase (L-AraDH) was induced. The enzyme was purified as a 130 kDa homotetrameric protein catalyzing the oxidation of L-arabinose with both ...

Applied Biochemistry and Biotechnology, 2011
We identified and characterized two genes, LAT1 and LAT2, which encode specific L: -arabinose transporters. The genes were identified in the L: -arabinose fermenting yeast Ambrosiozyma monospora. The yeast Saccharomyces cerevisiae had only very low L: -arabinose transport activity; however, when LAT1 or LAT2 was expressed, L: -arabinose transport was ...

Candida arabinofermentans, a new L-arabinose fermenting yeast
Antonie van Leeuwenhoek, 1998Candida arabinofermentans (type strain NRRL YB-2248, CBS 8468), a new yeast that ferments the pentose L-arabinose, is described. The three known strains of this new species were isolated from insect frass of pine and larch trees in the U.S. Phylogenetic analysis of nucleotide sequences from the D1/D2 domain of large subunit (26S) ribosomal DNA places C.

NEW SYNTHESIS OF L-FMAU FROM L-ARABINOSE
Nucleosides, Nucleotides and Nucleic Acids, 2002A new synthesis of 2'-deoxy-2'-fluoro-5-methyl-beta-L-arabinofuranosyl uracil (13, L-FMAU) was achieved in 10 steps from L-arabinose.

Biotechnological production of l-ribose from l-arabinose
Applied Microbiology and Biotechnology, 2009L-Ribose is a rare and expensive sugar that can be used as a precursor for the production of L-nucleoside analogues, which are used as antiviral drugs. In this work, we describe a novel way of producing L-ribose from the readily available raw material L-arabinose.

Enantiospecific Synthesis of Polyoxamic Acid from L-Arabinose
Synthesis, 1989Abstract Polyoxamic acid, 2-amino-2-deoxy-L-xylonic acid, is synthetized by thiophenoxide opening of a five-carbon chiral hydroxylated aziridine easily derived from L-arabinose. The formation of the carboxy group resulted from a Pummerer reaction.

Isopropylidenation of L-arabinose N,N-dimethylhydrazone
Collection of Czechoslovak Chemical Communications, 1985Direct isopropylidenation of L-arabinose N,N-dimethylhydrazone (I) was studied. Four major products whose structures were proven were produced in varying ratios depending upon the conditions. 2,2-Dimethoxypropane and sulfuric acid at 20 °C gave a 36% yield of 2,3:4,5-di-O-isopropylidene-L-arabinose N,N-dimethylhydrazone (II).
