Application
Phosphoriboisomerase is used to study the ribulose monophosphate pathway. Phosphoriboisomerase from spinach is used in enzyme assays to convert ribose 5-phosphate to ribulose 5-phosphate.
Biochem/physiol Actions
Phosphoriboisomerase is responsible for the converstion of ribose 5-phosphate to ribulose 5-phosphate.
Other Notes
One unit will convert 1.0 μmole of D-ribose 5-phosphate to D-ribulose 5-phosphate per min at pH 7.7 at 30 °C.

Two previously unreported inborn errors of metabolism occur in the reversible part of the pentose phosphate pathway. Deficiency of ribose-5-phosphate isomerase has been described in one patient who suffered from a progressive leukoencephalopathy and developmental delay. Transaldolase deficiency has been

Rare sugars are used for many industrial and medical purposes and are produced by the interconversion between aldoses and ketoses catalyzed by sugar and sugar-phosphate isomerases. Recently, Clostridium thermocellum d-ribose-5-phosphate isomerase (CTRPI), an aldose-ketose isomerase, was cloned in order to
