Protein Structure
Protein Structure
Proteins are made up of amino acids linked together in a chain. This chain folds into a specific three-dimensional structure, which is crucial for its function.
N and C Termini
N and C Termini
The N-terminal amino acid is the first amino acid in a protein chain, while the C-terminal amino acid is the last.
Protein structure by X-ray Crystallography
Protein structure by X-ray Crystallography
X-ray crystallography is a technique used to determine the three-dimensional structure of proteins. A protein crystal is bombarded with X-rays, and the diffraction pattern is analyzed to create a 3D model.
