The complexes are reduced by 0.5 equivalents of dithionite to form the corresponding semiquinones (λmax ~ 460 - 475 nm). An enzyme bound dihydrolumazine species cannot be obtained by direct reduction of the oxidized complexes; 7,8-dihydrolumazine is modified upon binding to apoflavodoxin (λmax ~ 400 nm) suggesting formation of a different tautomer, possibly the S,8-dihydro form. The apoflavodoxin complexes of 1 and 2 show a catalytic activity, ~ 30% and ~ 90% that of the native enzyme in the photosynthetic NADP reduction of spinach chloroplasts. This allows the deduction that electron transfer in flavodoxins does not occur simply via the flavin C(8) position.</dcterms:abstract> </rdf:Description> </rdf:RDF>
