Thanks for the comments. �We presume that the PFK either exists already in an altered state via phosphorylation to change its physical characteristics or that it must be a radically different isozyme of PFK. �PFK is known to be terribly sensitive to polymerization/depolymerization and temperature may have a significant
role in this process. �As to a PFK with a Q10 of 3.6 already existing - �I don't know of another PFK that has a Q10 in this range but most of the invertebrate PFKs have not been tested for temperature effects by themselves. �
