Subject: exposing your Tev site From: "Lukacs, Christine" christine {- dot -} lukacs {- at -} ROCHE {- dot -} COM Date: 2007-04-20
Quick question about Tev sites - We have a situation where our N-terminal TEV site is inaccessible to the protease. Looking at a close homolog, we realized that our first protein residue is already involved in a beta sheet. From peoples' experience - how FEW residues can we add between the cleavage site and the first protein residue in order to make the cleavage site accessible to the protease for efficient cleavage of the tag? (Tagged protein behaves well but crystallizes poorly, we are hoping that cleavage of the tag will improve things)
Thanks for any anecdotes- Christine Lukacs Roche
