Sorry, no etymologies found.
The specificity of glucose-6-P isomerase is unusual.
< 1, 3 > [2, 3] S Additional information (molecular mechanism of intracellular degradation of type I collagen in normal corneal endothelial cells, role of the enzyme and protein-disulfide isomerase, which is the b subunit of the enzyme, during procollagen I biosynthesis )  P?
The region includes genes encoding a CoA-dependent methylmalonate semialdehyde dehydrogenase (dntE), a putative NADH-dependent dehydrogenase (ORF13), and a bifunctional isomerase/hydrolase (dntG).
What, on earth, compelled anyone to use xylose isomerase and oligosaccharides in the first place?
The product is manipulated, using a process that includes alpha-amylase, oligosaccharides, and xylose isomerase, into a syrup that is anywhere from 90% fructose/10% glucose to 42% fructose/58% glucose.
We had been mistakenly unsuccessful in not finding the small amount of transfer that was later detected in the triose P isomerase reaction.
When G6P was used with isomerase in D2O the colorimetric analysis for fructose-6-P passed through a maximum before reaching a final value.
In unrelated experiments I observed a puzzling phenomenon with G6P isomerase.
Aconitate isomerase catalyzes the interconversion of cis - and trans-aconitate by a 1, 3 allylic rearrangement that uses the (pro-S) hydrogens of the two substrates.
The physical separation of H - from D-labeled molecules made possible by their different rates of reaction was used to establish that the transfer of hydrogen in G6P isomerase was intramolecular9 and that the site of attachment of CO2 to ribulose-1, 5-P2 to produce two molecules of phosphoglyceric acid had to be to C-2 rather than C-4 in the RUDP carboxylase reaction47.
