Protein design

This article refers to rational protein design. For the broader engineering of proteins see protein engineering.Protein design is the rational design of new protein molecules to fold to a target protein structure, with the ultimate goal of designing novel function and/or behavior. Proteins can be designed from scratch (de novo design) or by making calculated variations on a known protein structure and its sequence (known as protein redesign). Rational protein design approaches make protein-sequence predictions that will fold to specific structures. These predicted sequences can then be validated experimentally through methods such as peptide synthesis, site-directed mutagenesis, or artificial gene synthesis.Rational protein design dates back to the mid-1970s, although initial protein design approaches were based mostly on sequence composition and did not account for specific interactions between side-chains at the atomic level. Recently, however, improvements in molecular force fields, protein design algorithms, and structural bioinformatics, such as libraries of amino acid conformations, have enabled the development of advanced computational protein design tools. These computational tools can make complex calculations on protein energetics and flexibility, and perform searches over enormous configuration spaces, which would be unfeasible to perform manually. Thanks to the development of computational protein design programs and important successes in the field (e.g., see examples below), rational protein design has become one of the most important tools in protein engineering.
