Beschreibung

General description

D-Arabinose is a rare aldopentose, and is rarely utilized by enteric bacteria as a source of carbon and energy. It is also found in the aloins of the plant genus Aloe and as a constituent of the polysaccharide of the bacterial genus Mycobacterium. Some of the enteric bacteria like Escherichia coli K-12 can mutate to utilize D-arabinose.

Application

D-(-)-Arabinose has been used as an inducer of λ-RED recombinant gene expression.

Biochem/physiol Actions

D-Arabinose ist ein reduzierender Zucker. Sie ist ein Pentoseanalogon von D-Ribose, einem Bestandteil der Arabinogalactane von mykobakteriellen Zellwänden. Sie ist ebenfalls ein Substrat für die D-Erythroascorbinsäuresynthese in Hefe.
