This cofactor regeneration is classically done via an additional substrate, and if necessary enzyme. We now demonstrate an easy-to-apply cofactor regeneration approach, which can especially be used in screening applications. Simply by applying citrate to a buffer or directly using citrate/-phosphate buffer NADPH can be regenerated by native enzymes of the TCA cycle, practically present in all aerobic living organisms. Apart from viable-culturable cells, this regeneration approach can also be applied with lyophilized cells and even crude cell extracts. This is exemplarily shown for the synthesis of 1 phenylethanol from acetophenone with several oxidoreductases. The mechanism of NADPH regeneration by TCA cycle enzymes was further investigated by a transient isotopic labeling experiment feeding [1,5-13C]citrate. This revealed that the regeneration mechanism can further be optimized by genetic modification of two competing internal citrate metabolization pathways, the glyoxylate shunt and the glutamate dehydrogenase. 000858538 536__ $$0G:(DE-HGF)POF3-581$$a581 - Biotechnology (POF3-581)$$cPOF3-581$$fPOF III$$x0 000858538 588__ $$aDataset connected to CrossRef 000858538 7001_ $$0P:(DE-Juel1)169334$$aNeumann, Timo$$b1 000858538 7001_ $$0P:(DE-Juel1)129023$$aGätgens, Jochem$$b2 000858538 7001_ $$0P:(DE-HGF)0$$aRomano, Diego$$b3 000858538 7001_ $$0P:(DE-Juel1)129050$$aNoack, Stephan$$b4 000858538 7001_ $$0P:(DE-Juel1)144643$$aRother, Dörte$$b5$$eCorresponding author 000858538 773__ $$0PERI:(DE-600)2719493-0$$a10.3389/fbioe.2018.00196$$gVol. 6, p. 196$$p196$$tFrontiers in Bioengineering and Biotechnology$$v6$$x2296-4185$$y2018 000858538 8564_ $$uhttps://juser.fz-juelich.de/record/858538/files/2018-0123124-4.pdf 000858538 8564_ $$uhttps://juser.fz-juelich.de/record/858538/files/2018-0123124-4.pdf?subformat=pdfa$$xpdfa 000858538 8564_ $$uhttps://juser.fz-juelich.de/record/858538/files/fbioe-06-00196.pdf$$yOpenAccess 000858538 8564_ $$uhttps://juser.fz-juelich.de/record/858538/files/fbioe-06-00196.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000858538 8767_ $$82018-0123124-4$$92018-11-28$$d2018-12-14$$eAPC$$jDeposit$$lDeposit: Frontiers$$z1615 USD 000858538 909CO $$ooai:juser.fz-juelich.de:858538$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire$$pdnbdelivery 000858538 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)168384$$aForschungszentrum Jülich$$b0$$kFZJ 000858538 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129023$$aForschungszentrum Jülich$$b2$$kFZJ 000858538 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129050$$aForschungszentrum Jülich$$b4$$kFZJ 000858538 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)144643$$aForschungszentrum Jülich$$b5$$kFZJ 000858538 9131_ $$0G:(DE-HGF)POF3-581$$1G:(DE-HGF)POF3-580$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lKey Technologies for the Bioeconomy$$vBiotechnology$$x0 000858538 9141_ $$y2018 000858538 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000858538 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews 000858538 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000858538 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000858538 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000858538 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000858538 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review 000858538 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000858538 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000858538 915__ $$0StatID:(DE-HGF)0320$$2StatID$$aDBCoverage$$bPubMed Central 000858538 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000858538 9201_ $$0I:(DE-Juel1)IBG-1-20101118$$kIBG-1$$lBiotechnologie$$x0 000858538 980__ $$ajournal 000858538 980__ $$aVDB 000858538 980__ $$aUNRESTRICTED 000858538 980__ $$aI:(DE-Juel1)IBG-1-20101118 000858538 980__ $$aAPC 000858538 9801_ $$aAPC 000858538 9801_ $$aFullTexts
