Description

Application

L-Arabinose is used as a substrate to identify, differentiate and characterize pentose sugar isomerase(s). L-Arabinose is used in the bioproduction of L-ribose.

Biochem/physiol Actions

Le L-arabinose est un isomère présent naturellement comme constituant des polysaccharides de plantes. La plupart des bactéries contiennent un opéron arabinose inductible qui encode une série d′enzymes et de transporteurs permettant l′utilisation du L-arabinose comme unique source de carbone en culture bactérienne.
