Part:BBa_K608406
Precipitator
Protein domain of Precipitator. Artificial Leucine Rich Repeat(LRR) with C and N-terminal hagfish domain fragments capping the artifical middle part. This part is one version of three different designed to bind nickel by histidines, grouped together pointing away from the horseshoe shaped protein. This protein can be used to complex Nickel or Cobalt. The principal mechanism is comparable to Ni-NTA columns, as chelates the ions. Free binding sites of the ions are then exposed, so that a His-tagged protein can attach to them. The design of the protein is of a particular interest, too. LRR are highly conserved motifs throughout evolution. They appear in all kingdoms of life in almost every thinkable role (Ligases, Receptors, Toxins etc.). Their core is highly conserved and provides a very stable backbone, while the intermediate, non-conserved aminoacids are almost freely interchangeable.
This protein can be used to complex up to 4 Nickel or Cobalt. However the principal design oft he protein is of a particular interest, too. LRR are highly conserved motifs throughout evolution. They appear in all kingdoms of life in almost every thinkable role (Ligases, Receptors, Toxins etc.). Their core is highly conserved and provides a very stable backbone, while the intermediate, non-conserved aminoacids are almost freely interchangeable.
We only submitted one of the three versions, to reduce redundancy in the registry. Please contact us for any questions.
