Description

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[1].

Biochem/physiol Actions

Phosphoriboisomerase is responsible for the converstion of ribose 5-phosphate to ribulose 5-phosphate[1].

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.
