Knowra Protein engineering Protein engineering Protein engineering is the design or modification of proteins to alter their properties or create new functions, using experimental or computational methods.
Directed evolution : A method that improves biological molecules through repeated cycles of variation and selection. Repeated mutation and screening can optimize proteins without requiring a complete mechanistic model.
Amino acid : An organic molecule that serves as a building block of proteins. Changing amino acids is the basic way to alter a protein's sequence.
Monoclonal antibody : An antibody population produced from one cell lineage and directed against a specific target. Engineering can tune antibodies' binding, persistence, and interactions with immune cells.
Protein sequencing : The determination of the amino-acid order in a protein. Sequencing made protein composition measurable and comparable, enabling deliberate modification.
De novo protein design : The creation of proteins with designed sequences and structures rather than modification of natural proteins. It seeks new proteins from scratch, rather than adapting an existing protein scaffold.
Rational design : The deliberate design of molecules using structural, mechanistic, or computational knowledge. Protein engineers use structural hypotheses to choose specific amino-acid changes.
Protein structure : The three-dimensional arrangement of atoms in a protein, from local folds to whole-protein organization. Structure connects sequence changes to stability, binding, and catalytic activity.
Chimeric antigen receptor T cell : A T cell modified to express a synthetic receptor that recognizes a chosen target. Its engineered receptor combines protein domains to direct immune-cell recognition.
Frederick Sanger : A British biochemist who determined the amino-acid sequence of insulin. His sequencing work established that proteins have defined, investigable sequences.
Comparative protein modeling : The prediction of a protein's structure using a related protein with a known structure as a template. Template-based modeling supplies structural information often used in rational engineering.
