Low-barrier hydrogen bonds and unusual pKa values for the catalytic residues have been proposed as the basis for the fast action of KSI.

Mutations in IDI1, the gene that codes for IPP isomerase 1, have been implicated in decreased viability in a number of organisms, including the yeast Saccharomyces cerevisiae, the nematode Caenorhabditis elegans and the plant Arabidopsis thaliana.
Low phosphate levels inhibit GAP dehydrogenase; GAP is instead converted into DHAP by triosephosphate isomerase (Wikipedia Triosephosphate isomerase).
Phosphoribosylanthranilate isomerase is also found in various forms of fungi such as Kluyveromyces lactis (yeast), Saccharomyces cerevisiae (yeast), and Ashbya gossypii.
Ribose-5-phosphate isomerase deficiency is mutated in a rare disorder, Ribose-5-phosphate isomerase deficiency.
