Structure Based Combinatorics Combinatorial ProteinengineeringProteinEngineering SCOPE is a synthetic biology technique for creating gene library gene libraries lineage evolution lineages of defined composition designed from structural and probabilistic constraints of the encoded proteins. The development of this technique was driven by fundamental questions about protein structure , Protein Cellular functions function , and evolution, although the technique is generally applicable for the creation of engineered proteins with commercially desirable properties. Combinatorial Travel Through Sequence spacetime Space Time is the goal of SCOPE. At its inception, SCOPE was developed as a homology biology homology independent recombination technique to enable the creation of multiple crossover libraries from distantly related genes. In this application, an exon plate tectonics design strategy was devised to assemble equivalent elements of structure continental plates with variability in the junctions linking them fault geology fault lines to explore global protein space. To create the corresponding library of genes, the breeding scheme of Gregor Mendel was adapted into a Polymerase chain reaction PCR strategy to selectively cross hybrid genes, a process of Iteration iterative inbreeding to create all possible combinations of coding segments with variable linkages.

Protein purification is vital for the characterization of the function, structure and interactions of the protein of interest. The starting material is usually a biological tissue or a microbial culture. The various steps in the purification process may free the protein from a matrix that confines it, separate the protein and non protein parts of the mixture, and finally separate the desired protein from all other proteins.

C7 protein is an Proteinengineering engineered zinc finger protein based on the murine ZFP, Zif268 and discovered by Wu et al. in 1994 published in 1995 . It shares the same zinc finger 2 and zinc finger 3 of Zif268, but differs in the sequence of finger 1. It also shares the same DNA target, 5 GCGTGGGCG 3 . The shared sequences in Amino acid List of standard amino acids single letter amino acid codes of fingers 2 and 3 are RSD H LTT and RAD E RKR positions 1 through 6 in the alpha helix . Zinc finger 1 has the sequence KSA D LKR which provides a 13 fold increase in affinity to the target sequence of the entire ZFP over that of Zif268. It is used in zinc finger investigations in which the amino acid sequence of finger 2 is changed in order to determine the appropriate sequence to target a given three nucleotide target site. A variation of C7, C7.GAT protein C7.GAT is preferred since it lacks the aspartic acid residue present in finger 3 of C7 and known to cause a phenomenon called target site overlap . In this case the target site overlap is a result of the aspartic acid residue forming a hydrogen bond with the N4 of the cytosine in the opposite strand base paired to the guanine in the finger 2 subsite. It can also form the same hydrogen bond with an adenine base paired to a thymine. This target site overlap would dictate that either a cytosine or adenine residue be present as the 3 nucleotide in the finger 2 subsite which is unacceptable when looking to target sequences containing another nucleotide at this position.
