Editing Protein engineering (section)

===Enzyme engineering===
Enzyme engineering is the application of modifying an enzyme's structure (and, thus, its function) or modifying the catalytic activity of isolated [[enzyme]]s to produce new metabolites, to allow new (catalyzed) pathways for reactions to occur,<ref>{{cite news |title='Designer Enzymes' Created By Chemists Have Defense And Medical Uses |url=https://www.sciencedaily.com/releases/2008/03/080319160050.htm |work=ScienceDaily |date=March 20, 2008 }}</ref> or to convert from certain compounds into others ([[biotransformation]]). These products are useful as chemicals, pharmaceuticals, fuel, food, or agricultural additives.

An ''enzyme reactor'' <ref>{{cite web |url=http://www.lsbu.ac.uk/biology/enztech/reactors.html |title=Enzyme reactors |access-date=2013-11-02 |url-status=dead |archive-url=https://web.archive.org/web/20120502110325/http://www.lsbu.ac.uk/biology/enztech/reactors.html |archive-date=2012-05-02 }}</ref> consists of a vessel containing a reactional medium that is used to perform a desired conversion by enzymatic means. Enzymes used in this process are free in the solution. Also Microorganisms are one of important origin for genuine enzymes .<ref>{{Cite journal |last1=Sharma |first1=Anshula |last2=Gupta |first2=Gaganjot |last3=Ahmad |first3=Tawseef |last4=Mansoor |first4=Sheikh |last5=Kaur |first5=Baljinder |date=2021-02-17 |title=Enzyme Engineering: Current Trends and Future Perspectives |url=https://doi.org/10.1080/87559129.2019.1695835 |journal=Food Reviews International |volume=37 |issue=2 |pages=121–154 |doi=10.1080/87559129.2019.1695835 |s2cid=213299369 |issn=8755-9129|url-access=subscription }}</ref>
