(A tad delayed) Actually, typically we set up crystal trials for both cleaved and uncleaved protein right away at the same time (if there's enough protein and the cleavage works). Cheers phx On 07/01/2011 15:10, Bosch, Juergen wrote: I vaguely remember a paper by Aled Edwards, where they did

The RCSB PDB site (www.pdb.org) provides as sequence motif search as an advanced search option. For example to search for a N-terminal (His)6 tag, use the following regular expression: ^HH or HH to find any sequence with a (His)6 pattern. Click on this link to retrieve all seq

I vaguely remember a paper by Aled Edwards, where they did the statistics for their targets at SGC. As far as I recall they engineer with cleavable tag purify and cyrstallize it first with tag and only if they don't get crystals or a structure they cleave off the tag and rerun the screens. I thi
