The uptake of the paramagnetic ion manganese by rat liver mitochondria is studied by electron paramagnetic resonance (EPR) spectroscopy. Emphasis is placed on: (a) obtaining accurate EPR quantitation of intramitochondrial manganese fractions previously described (Gunter, T. E., and J. S.Puskin, 1972, Biophys. J. 12:625) (b) establishing competition for intramitochondrial binding between one of these fractions and calcium, (c) demonstrating the effects of substrate and ATP concentrations on each fraction observed through EPR, and (d) demonstrating the effect of inorganic phosphate (Pi) concentration and pH on each fraction.
通过电子顺磁共振(EPR)光谱研究大鼠肝脏线粒体对顺磁性离子锰的摄取。重点在于:(a)对先前描述的线粒体内锰组分进行准确的EPR定量分析(冈特,T.E.,和J.S.普斯金,1972年,《生物物理杂志》12:625);(b)确定这些组分之一与钙在线粒体内结合的竞争关系;(c)通过EPR证明底物和ATP浓度对每个观察到的组分的影响;以及(d)证明无机磷酸盐(Pi)浓度和pH值对每个组分的影响。
