Do you know some enzyme that consequently isomerases and oxidases a substrate? what class would it be? Oxidase?
Cholesterol oxidase performs an oxidation followed by an isomerization. It belongs to the oxidase class (EC 1.1.3.6).

Ketol-acid reductoisomerase (EC 1.1.1.81) is another example. In the non-physiological direction there is an oxidation (by NADP+) followed by an isomerisation.
I think UDP epimerase would classify as this. It does an oxidation/reduction that results in an epimerization reaction.
When I get results from sequencing, they often overlap only partly or not at all. In such case it's easier to align them with the "parental" sequence (of what I expect), to see where they align....
