We report a comparative study of the photocycles of the isolated, light-sensitive domains LOV1 and LOV2 from Chlamydomonas reinhardtii phot protein, as well as the construct LOV1/2 containing both domains. Transient absorption measurements revealed a short lifetime of the LOV2-wt triplet state (500 ns), but a long lifetime (287 micros) of the triplet in the mutant LOV2-C250S, in which the reactive cysteine is replaced by serine. For LOV1, in comparison, corresponding numbers of 800 ns and 4 micros for the two conformers in LOV1-wt, and 27 micros for LOV1-C57S have been reported. The triplet decay kinetics in the mixed domains LOV1/2-wt, LOV1/2-C57S, and LOV1/2-C250S can be analyzed as the superposition of the behavior of the corresponding single domains. The situation is different for the slow, thermal reaction of the photoadduct back to the dark form. Whereas the individual domains LOV1 and LOV2 show two decay components, the double domains LOV1/2-C57S and LOV1/2-C250S both show only a single component. The interaction of the two domains does therefore not manifest itself during the lifetime of the triplet states, but changes the decay behavior of the adduct states. 000049345 536__ $$0G:(DE-Juel1)FUEK255$$2G:(DE-HGF)$$aNeurowissenschaften$$cL01$$x0 000049345 588__ $$aDataset connected to Web of Science, Pubmed 000049345 650_2 $$2MeSH$$aAnimals 000049345 650_2 $$2MeSH$$aAnions 000049345 650_2 $$2MeSH$$aCations 000049345 650_2 $$2MeSH$$aChlamydomonas reinhardtii: metabolism 000049345 650_2 $$2MeSH$$aCryptochromes 000049345 650_2 $$2MeSH$$aCysteine: chemistry 000049345 650_2 $$2MeSH$$aDNA Adducts 000049345 650_2 $$2MeSH$$aFlavoproteins: chemistry 000049345 650_2 $$2MeSH$$aHot Temperature 000049345 650_2 $$2MeSH$$aHydrogen-Ion Concentration 000049345 650_2 $$2MeSH$$aIons 000049345 650_2 $$2MeSH$$aKinetics 000049345 650_2 $$2MeSH$$aLight 000049345 650_2 $$2MeSH$$aModels, Chemical 000049345 650_2 $$2MeSH$$aMutation 000049345 650_2 $$2MeSH$$aPhotons 000049345 650_2 $$2MeSH$$aPhotoreceptor Cells, Invertebrate: chemistry 000049345 650_2 $$2MeSH$$aProtein Binding 000049345 650_2 $$2MeSH$$aProtein Structure, Tertiary 000049345 650_2 $$2MeSH$$aSerine: chemistry 000049345 650_2 $$2MeSH$$aSodium Chloride: pharmacology 000049345 650_2 $$2MeSH$$aSpectrophotometry 000049345 650_2 $$2MeSH$$aTemperature 000049345 650_2 $$2MeSH$$aTime Factors 000049345 650_7 $$00$$2NLM Chemicals$$aAnions 000049345 650_7 $$00$$2NLM Chemicals$$aCations 000049345 650_7 $$00$$2NLM Chemicals$$aCryptochromes 000049345 650_7 $$00$$2NLM Chemicals$$aDNA Adducts 000049345 650_7 $$00$$2NLM Chemicals$$aFlavoproteins 000049345 650_7 $$00$$2NLM Chemicals$$aIons 000049345 650_7 $$052-90-4$$2NLM Chemicals$$aCysteine 000049345 650_7 $$056-45-1$$2NLM Chemicals$$aSerine 000049345 650_7 $$07647-14-5$$2NLM Chemicals$$aSodium Chloride 000049345 650_7 $$2WoSType$$aJ 000049345 7001_ $$0P:(DE-Juel1)VDB16784$$aKottke, T.$$b1$$uFZJ 000049345 7001_ $$0P:(DE-HGF)0$$aHegemann, P.$$b2 000049345 7001_ $$0P:(DE-HGF)0$$aDick, B.$$b3 000049345 773__ $$0PERI:(DE-600)1477214-0$$a10.1529/biophysj.104.058230$$gVol. 89, p. 402 - 412$$p402 - 412$$q89<402 - 412$$tBiophysical journal$$v89$$x0006-3495$$y2005 000049345 8567_ $$2Pubmed Central$$uhttp://www.ncbi.nlm.nih.gov/pmc/articles/PMC1366540 000049345 8564_ $$uhttps://juser.fz-juelich.de/record/49345/files/77245.pdf$$yOpenAccess 000049345 8564_ $$uhttps://juser.fz-juelich.de/record/49345/files/77245.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000049345 8564_ $$uhttps://juser.fz-juelich.de/record/49345/files/77245.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000049345 8564_ $$uhttps://juser.fz-juelich.de/record/49345/files/77245.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000049345 909CO $$ooai:juser.fz-juelich.de:49345$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000049345 9131_ $$0G:(DE-Juel1)FUEK255$$bLeben$$kL01$$lFunktion und Dysfunktion des Nervensystems$$vNeurowissenschaften$$x0 000049345 9141_ $$y2005 000049345 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000049345 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000049345 9201_ $$0I:(DE-Juel1)VDB58$$d31.12.2006$$gIBI$$kIBI-2$$lBiologische Strukturforschung$$x0 000049345 970__ $$aVDB:(DE-Juel1)77245 000049345 9801_ $$aFullTexts 000049345 980__ $$aVDB 000049345 980__ $$aJUWEL 000049345 980__ $$aConvertedRecord 000049345 980__ $$ajournal 000049345 980__ $$aI:(DE-Juel1)ISB-2-20090406 000049345 980__ $$aUNRESTRICTED 000049345 980__ $$aI:(DE-Juel1)ICS-6-20110106 000049345 980__ $$aFullTexts 000049345 981__ $$aI:(DE-Juel1)IBI-7-20200312 000049345 981__ $$aI:(DE-Juel1)ISB-2-20090406 000049345 981__ $$aI:(DE-Juel1)ICS-6-20110106
