The lysozyme was first noticed during some investigations made on a patient suffering from acute coryza. [15] This was the first recorded discovery of lysozyme. With Allison, he published further studies on lysozyme in October issue of the British Journal of Experimental Pathology the same year. [17]

Abraham completed his DPhil at the University of Oxford under the supervision of Sir Robert Robinson, during which he was the first to crystallise lysozyme, [1] [7] an enzyme discovered by Sir Alexander Fleming and shown to have antibacterial properties, and was later the first enzyme to have its structure solved using X-ray crystallography, by ...
In the contaminated plate the bacteria around the mould did not grow, while those farther away grew normally, meaning that the mould killed the bacteria. [6] Fleming commented as he watched the plate: "That's funny". [5] [6] Pryce remarked to Fleming: "That's how you discovered lysozyme."
This was first done for lysozyme, an enzyme found in tears, saliva and egg whites that digests the coating of some bacteria; the structure was solved by a group led by David Chilton Phillips and published in 1965. [18]
Finally, the recently discovered γ-d-glutaminyl-l-lysine endopeptidase lysins cleave the gamma bond between D-glutamine and L-lysine residues. As is the case for autolysins , early confusion around the cleavage specificity of these individual enzymes has led to some misattributions of the name "lysozyme" to proteins without this activity.
US penicillin production rose from 21.192 billion units in 1943, to 1,663 billion units in 1944, and an estimated 6,852 billion units in 1945. [156] By June 1944, Pfizer alone was producing 70 billion units per month. [157] Monthly production dropped off after July 1945 due to a shortage of corn-steep liquor.
Many species of bacteria are subject to lysis by the enzyme lysozyme, found in animal saliva, egg white, and other secretions. [1] Phage lytic enzymes produced during bacteriophage infection are responsible for the ability of these viruses to lyse bacterial cells. [2]
