Summary for Patent: 5,780,279
| Title: | Method of selection of proteolytic cleavage sites by directed evolution and phagemid display |
| Abstract: | A method for identifying and selecting novel substrates for enzymes is provided. The method comprises constructing a gene fusion comprising DNA encoding a polypeptide fused to DNA encoding a substrate peptide, which in turn is fused to DNA encoding at least a portion of a phage coat protein. The DNA encoding the substrate peptide is mutated at one or more codons thereby generating a family of mutants. The fusion protein is expressed on the surface of a phagemid particle and subjected to chemical or enzymatic modification of the substrate peptide. Those phagemid particles which have been modified are then separated from those that have not. |
