Application
L-Ribulose has been used as a substrate in L-arabinose isomerase activity assay and in ribulokinase activity assay.
Biochem/physiol Actions
L-Ribulose is produced from L-ribose by microbial enzymes. L-Ribulose is a rare sugar and a precursor for antiviral drugs synthesis. Major industrial production of L-ribulose is by the use of L-arabinose isomerase enzyme.
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.

A newly isolated bacterium, Cellulomonas parahominis MB426, produced l-ribose isomerase (CeLRI) on a medium containing l-ribose as a sole carbon source. A 32 kDa protein isomerizing l-ribose to l-ribulose was purified to homogeneity from this bacterium. A set of degenerated

A new high performance liquid chromatographic (HPLC) method is described for the analysis of ribose, arabinose and ribulose mixtures obtained from (bio)chemical isomerization processes. These processes gain importance since the molecules can be used for the synthesis of antiviral therapeutics.

L-Ribulose is a rare and expensive sugar that can be used as a precursor for the production of other rare sugars of high market value such as L-ribose. In this work we describe a production process for L-ribulose using L-arabinose
