Need GTPase for positive control

I am doing some GTPase assays and would like to obtain an enzyme with
intrinsic GTPase activity to use as a positive control.  Does anyone know
of a commercially available GTPase that I could use (or a source of a
non-commercial enzyme).  If it requires a GAP, I would also need to obtain
that as well, but I would prefer a GTPase that has significant activity
(Kcat.GTP ~ 1-5 per min.) by itself.
