The problem is that there are tens of isoschizomers out there, the vast 
majority un-commercialised. I must have at least a  hundred from our 
screenings, some of which have been licensed off, the rest just sit 
there and have never been made in more than mostly crude extracts for 
screening. There are 586 RE's commercially available. If you have the 
time and money the iso's could be compared but ......

I don't know if REBASE (http://rebase.neb.com/rebase/) has more info. on 
iso. comparisons but I would doubt it.

REBASE enzyme #: 3829
