Rubredoxins are a ubiquitous [1Fe-0S] class of electron carriers that play an important role in bacterial adaptation to changing environmental conditions. In Mycobacterium tuberculosis, oxidative and acidic stresses as well as iron starvation induce rubredoxins expression. However, their functions during M. tuberculosis infection are unknown. In the present work, we show that rubredoxin B (RubB) is able to efficiently shuttle electrons from cognate reductases, FprA and FdR to support catalytic activity of cytochrome P450s, CYP124, CYP125, and CYP142, which are important for bacterial viability and pathogenicity. We solved the crystal structure of RubB and characterized the interaction between RubB and CYPs using site-directed mutagenesis. Mutations that not only neutralize single charge but also change the specific residues on the surface of RubB did not dramatically decrease activity of studied CYPs. Together with isothermal calorimetry (ITC) experiments, the obtained results suggest that interactions are transient and not highly specific. The redox potential of RubB is −264 mV vs. Ag/AgCl and the measured extinction coefficients are 9931 M−1cm−1 and 8371 M−1cm−1 at 380 nm and 490 nm, respectively. Characteristic parameters of RubB along with the discovered function might be useful for biotechnological applications. Our findings suggest that a switch from ferredoxins to rubredoxins might be crucial for M. tuberculosis to support CYPs activity during the infection. 000904321 536__ $$0G:(DE-HGF)POF4-5241$$a5241 - Molecular Information Processing in Cellular Systems (POF4-524)$$cPOF4-524$$fPOF IV$$x0 000904321 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000904321 7001_ $$0P:(DE-HGF)0$$aKavaleuski, Anton$$b1 000904321 7001_ $$0P:(DE-HGF)0$$aGrabovec, Irina$$b2 000904321 7001_ $$0P:(DE-HGF)0$$aKavaleuskaya, Anna$$b3 000904321 7001_ $$0P:(DE-HGF)0$$aVakhrameev, Daniil$$b4 000904321 7001_ $$0P:(DE-HGF)0$$aBukhdruker, Sergey$$b5 000904321 7001_ $$0P:(DE-HGF)0$$aMarin, Egor$$b6 000904321 7001_ $$0P:(DE-HGF)0$$aKuzikov, Alexey$$b7 000904321 7001_ $$0P:(DE-HGF)0$$aShumyantseva, Victoria$$b8 000904321 7001_ $$0P:(DE-HGF)0$$aMasamrekh, Rami$$b9 000904321 7001_ $$0P:(DE-HGF)0$$aTsumoto, Kouhei$$b10 000904321 7001_ $$0P:(DE-Juel1)191126$$aBorshchevskiy, Valentin$$b11$$ufzj 000904321 7001_ $$0P:(DE-HGF)0$$aStrushkevich, Natallia$$b12 000904321 7001_ $$0P:(DE-HGF)0$$aGilep, Andrei$$b13$$eCorresponding author 000904321 773__ $$0PERI:(DE-600)1462232-4$$a10.1016/j.bioorg.2021.104721$$gVol. 109, p. 104721 -$$p104721 -$$tBioorganic chemistry$$v109$$x0045-2068$$y2021 000904321 8564_ $$uhttps://juser.fz-juelich.de/record/904321/files/2020.10.27.356691v1.full.pdf$$yOpenAccess 000904321 909CO $$ooai:juser.fz-juelich.de:904321$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000904321 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)191126$$aForschungszentrum Jülich$$b11$$kFZJ 000904321 9131_ $$0G:(DE-HGF)POF4-524$$1G:(DE-HGF)POF4-520$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5241$$aDE-HGF$$bKey Technologies$$lNatural, Artificial and Cognitive Information Processing$$vMolecular and Cellular Information Processing$$x0 000904321 9141_ $$y2021 000904321 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)1050$$2StatID$$aDBCoverage$$bBIOSIS Previews$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)1190$$2StatID$$aDBCoverage$$bBiological Abstracts$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)1200$$2StatID$$aDBCoverage$$bChemical Reactions$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)1030$$2StatID$$aDBCoverage$$bCurrent Contents - Life Sciences$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)1210$$2StatID$$aDBCoverage$$bIndex Chemicus$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000904321 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bBIOORG CHEM : 2019$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2021-01-27 000904321 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2021-01-27$$wger 000904321 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2021-01-27 000904321 9201_ $$0I:(DE-Juel1)IBI-7-20200312$$kIBI-7$$lStrukturbiochemie$$x0 000904321 980__ $$ajournal 000904321 980__ $$aVDB 000904321 980__ $$aUNRESTRICTED 000904321 980__ $$aI:(DE-Juel1)IBI-7-20200312 000904321 9801_ $$aFullTexts
