Re: [ccp4bb] DNA Protein co- Crystallization

We have limited experience in protein:DNA crystallization (N=1), but this is what worked for us a few years ago. Like others have advised, I also suggest using oligos with different ends. We tested two protein constructs, one with a a TEVP cleavable N-terminal His tag and the other with a

Hi, I'm working on DNA binding protein, looking to co-crystallize protein- DNA complex and have no previous experience. Your suggestion would be very precious on the following queries. 1. My protein is 646 amino acid long and it exists as homodimer. It is also having around 20 amino acid

Dear All, For the question, I think for a protein-DNA interaction, the protein may interact with any sequences of DNA, which will give a lot of combination of protein-DNA sequence for crystallization screening.  Or do anyone regard to just try the crystallization of the protein-one specific
