John, I don't know what kind of GTPase assays you're doing and how pure you need the proteins to
be, but most membrane preps will contain G-proteins which have an intrinsic GTPase activity in
the range you're looking for. I don't know if the purified proteins are commercially available
(if you use Gi or Go, you shouldn't need any GAP), but I think that if you wanted purified
G-proteins someone like Paul Sternweis might be the person to ask.
E-mail me for more info, if you're interested.
