Hello All,
I have been working on a structure for one of the research groups here
and have come across a peptide fragment of about 10 residues. The
protein forms a tetramer and the peptide is found between two of the
monomers. The protein itself does not require a peptide for function
or formation for that matter. Has anyone come across similar things?
and have a reference. We are trying to figure out where it may have
come from. My best guess so far is from somewhere in the purification
though I have no idea how long the protein sat around before
crystallization.
Cheers,
