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.

Ribose-5-phosphate isomerase is an enzyme that catalyzes the interconversion of ribose-5-phosphate and ribulose-5-phosphate. This family of enzymes naturally occurs in two distinct classes, RpiA and RpiB, which play an important role in the pentose phosphate pathway and nucleotide and co-factor

Ribose 5-phosphate isomerase (RPI) deficiency is an enzymopathy of the pentose phosphate pathway. It manifests with progressive leukoencephalopathy and peripheral neuropathy and belongs, with one sole diagnosed case, to the rarest human disorders. The single patient was found compound heterozygous

This paper describes optimization of electrotransformation of Mu transposition complexes into Lactococcus lactis cells and identification of genes affecting nisin production. The highest transformation efficiency, 1.1 x 10(2) transformants microg(-1) of input transposon DNA, was achieved when cells were grown

The activity of ribose-5-phosphate isomerases (RpiB) from Clostridium difficile for D-ribose isomerization was optimal at pH 7.5 and 40 degrees C, while that from Thermotoga maritima for L-talose isomerization was optimal at pH 8.0 and 70 degrees C. C. difficile

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
