Magnetic field effects in adenosylcob(III)alamin photolysis : relevance to B12 enzymes

摘要: The magnetic field dependence of geminate radical pair recombination following the photolysis adenosylcob-(III)alamin (AdoCbl III ) has been studied by continuous-wave and picosecond laser flash technique. net quantum yield (O) for 514-nm AdoCbl is decreased 2-fold at 80 mT in aqueous 75% glycerol 1.8-fold 50 20% Ficoll-400. No observed H 2 O. Glycerol a microviscosigen that enhance decreasing diffusion, whereas Ficoll-400 macroviscosigen enhances forming «cage» structure solution
