from two to four orthogonal oriented directions. Free binding sites of the ions are then exposed, so that a His-tagged protein can attach to them. This protein can be used to complex up to 4 Nickel or Cobalt.

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 non-conserved aminoacids are almost freely interchangeable.

LRRs 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 non-conserved aminoacids are almost freely interchangeable.  
Here we investigated an optimal set of non-conserved aminoacids by analysing large sets of similar proteins and databases. You can use this piece of work as a template to design your own protein and give it any function you like, by simply interchanging aminoacids and fusing other domains on the N or C termini. To guarantee proper folding and to shield off the hydrophobic core, a well studied fragment of an LRR protein coming from hagfish was used. This efficiency of this technique was proven before.(REFERENZ). To find out the most likely folding, we designed many different protein sequences, trying out a variety of sets of non coding aminoacids for the LRR and submitted these to the I-TASSER structure prediction
