PEP-dependent formation of [14C]ATP from [14C]ADP. Synaptic vesicles (40 μg) were incubated at 30°C for 10 min with 0.2 mM [14C]ADP (0.66 mCi/mmol) in the absence or presence of 1 mM PEP in the standard medium (final volume, 0.3 ml) described in Materials and Methods. The mixture was double-filtered, and aliquots (0.1 ml) analyzed by HPLC, as described in Materials and Methods. The data represent mean ± SEM of three vesicle preparations. PEP − vs. PEP +: * p < 0.05; ** p < 0.01.
