Properties of glutamate dehydrogenase in developing legume fruit. II.The effects of divalent cations.

The activity of EDTA-inhibited glutamate dehydrogenase from a crude seed extract of Lupinus angustifolius could be partially or fully restored by the addition of divalent cations to the incubation mixture. Mn2+ and Ca2+ gave the highest stimulations of 67% and 66% of the control, respectively; fol...
