Enzymes are produced by microorganisms. These microorganisms can be modified to produce enzymes with much better yield properties and purity. Such GMMs (genetically modified micro-organisms) are however not part of the final enzyme product.

Enzymes basically work due to the lock and key theory, where the substrate substance (the key) fits into the active site on the enzyme and they bind together, the reaction takes place and the substrate unlocks to
