Emil Fischer's lock and key model assumes that the active site is a perfect fit for a specific substrate and that once the substrate binds to the enzyme no further modification occurs.
According to Fisher’s lock-and-key model proposed by Hermann Emil Fischer in 1884 and Koshland’s induced fit theory by Daniel E. Koshland, Jr. in 1958, given a peptide, the prerequisite condition for it to be cleaved by HIV-protease is a good fit and binding between the substrate and the enzyme’s active site.
After a two year time working with Hermann Emil Fischer in Berlin Semmler accepted a position at the University of Breslau.
In addition to his work in the fields already mentioned, Fischer also studied the enzymes and the chemical substances in the lichens which he found during his frequent holidays in the Black Forest, and also substances used in tanning and, during the final years of his life, the fats.

Barbitone was first synthesized in 1902 by German chemists Emil Fischer and Joseph von Mering.
This understanding occurred largely as a result of the investigations of Emil Fischer, a German chemist who received the 1902 Nobel Prize in Chemistry as a result of his findings.
In 1911 he was awarded an 1851 Exhibition Scholarship, which allowed him to study for three semesters in Berlin under Emil Fischer, and one semester with A. W. Stewart at Queen's College, Belfast.
