Enzymes (ˈɛnzaɪmz) are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps.
Phage display is a laboratory technique for the study of protein–protein, protein–peptide, and protein–DNA interactions that uses bacteriophages (viruses that infect bacteria) to connect proteins with the genetic information that encodes them. In this technique, a gene encoding a protein of interest is inserted into a phage coat protein gene, causing the phage to "display" the protein on its outside while containing the gene for the protein on its inside, resulting in a connection between genotype and phenotype.
We present a new antibody-directed enzyme prodrug therapy strategy (ADEPT) based on a post-proline cleaving endopeptidase and prodrugs, in which cytotoxic moieties are linked to a proline-contg. pepti

The procedures for calmodulin-tagged phage and two-filter sandwich assays for the isolation of enzymic activities are presented. In the first method, enzymes are displayed on filamentous phage, and th
