摘要：

Energized mitochondria showed an ADP-induced contraction which was partially resistant to oligomycin, uncouplers or respiratory inhibitors but sensitive to atractyloside. The addition of ADP or ATP, but not AMP, to non-energized corn mitochondria induced a contraction with a Kd of approx. 1 .mu.M. Titration of the ADP-induced contraction with atractyloside produced an inhibition curve closely resembling the atractyloside inhibition curve of phosphorylating respiration. Partial recovery of atractyloside-inhibited contraction occurred in the presence of bongkrekic acid. These changes may reflect changes in orientation of the adenine nucleotide (AdN) carrier in the inner mitochondrial membrane.
