Ah, but what I'm getting at is that the behavior of complex molecules
is technically independent of evolution, so although organisms may
make use of a given active site, there may be others that either
are used, or not.

Anyway I googled for "multiple active sites" and enzyme, and
quite a few references appeared to enzymes that have them,
but I will have to look over the webpages to see if it's just
semantics or really multiple active sites.

For example:
