Influence of adenine nucleotides on the inhibition of photophosphorylation in spinach chloroplasts by N-ethylmaleimide.


The incubation of spinach chloroplasts with 1 mM N-ethylmaleimide in light for 60 to 90 s results in a partial, irreversible inhibition of photophosphorylation. The inhibition was not overcome at infinite light intensity or at infinite concentrations of the phosphorylation substrates. Although the inhibition diminished with decreasing concentrations of… (More)
