Enzymes are proteins that act as biological catalysts (biocatalysts). They can be used as stereoselective industrial biocatalysts. She studies the interface between biocatalysts and electrode surfaces for bioelectrocatalysis. Biodiesel and related biofuels require processing via both inorganic and biocatalysts. Flavoproteins are ubiquitous biocatalysts binding specific redox active prosthetic groups. Biocatalysts (enzymes) are often seen as a separate group. Enzymes and other biocatalysts are often considered as a third category. Other biocatalysts are catalytic RNA molecules, called ribozymes. The reaction can also be accomplished with the help of enzymes (biocatalysts) particularly lipases (E.C.3.1.1.3). Codexis engineers custom enzymes and microorganisms, which are sometimes referred to as biocatalysts. CodeEvolver combines DNA shuffling and bioinformatics with systems biology to create new biocatalysts. These biocatalysts can be employed to create various chemicals for pharmaceutical or other purposes. CLEAs are very attractive biocatalysts, owing to their facile, inexpensive and effective production method.
