Abstract
Phillips had been there since 1956 and had begun working on the structure of the antibacterial protein lysozyme. Besides being part of the team tackling this task, Johnson set out to explore a related issue: the position on the molecule of the site responsible for its catalytic action. Johnson retired from Oxford University in 2007, but continued working. Since 2003 she had spent half her time as the Director of Life Sciences for the Diamond Light Source, the UK's national research synchrotron facility for generating powerful beams of radiation ranging from infrared to x-rays.
