Professor Dame Louise Napier Johnson, DBE, FRS (26 September 1940 - 25 September 2012), was a British biochemist and protein crystallographer. She was David Phillips Professor of Molecular Biophysics at the University of Oxford from 1990 to 2007, and later an emeritus professor.
She was a Fellow of Corpus Christi College and an Honorary Fellow of Somerville College. In 2004 she was awarded an Honorary Degree from the University of Bath. She was elected a foreign associate of the US National Academy of Sciences.
She was part of the team, begun by William Lawrence Bragg and later led by David Phillips, that discovered the structure of the enzyme lysozyme; this was the third protein structure ever solved by x-ray crystallography, and the first enzyme. She also worked with Fred Richards and Hal Wyckoff on the structure of ribonuclease S, the fourth protein structure solved. Johnson's own lab at Oxford solved and studied many other protein structures, and she is a depositor on 100 PDB entries including many forms of glycogen phosphorylase and of cell cycle CDK/cyclin complexes Together with Tom Blundell, she wrote an influential textbook on protein crystallography.
