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 ...

One-Pot Bioconversion of l-Arabinose to l-Ribulose in an Enzymatic Cascade.
Angewandte Chemie, 2019This 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.

l -arabinose isomerases: Characteristics, modification, and application
Trends in Food Science & Technology, 2018Background d -Tagatose, a ketose isomer of d -galactose, is a kind of rare sugar existing in nature. The sweetness of d -tagatose is comparable to that of sucrose, but d -tagatose has a relatively lower energy content, indicating that it is an ideal ...

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 ...

Novel stereospecificity of the L-arabinose-binding protein
Nature, 1984Tertiary structure refinement at 1.7 A resolution of the liganded form of L-arabinose-binding protein from Escherichia coli has revealed a novel binding site geometry which accommodates both alpha- and beta-anomers of L-arabinose. This detailed structure analysis provides new understanding of protein-sugar interaction, the process by which the binding ...
