Having the protease site too close to the protein can often make it difficult to cut. Cheers, Charlie Quotfintg Jacob Keller > I checked out the Sheffield et al paper, and the restriction sites > there are all just after the TEV site, thereby including, as Cynthia > mentioned, at least an extra H beyond the obligatory G from the TEV > site.
