title: ATP-released large subunits participate in the assembly of RuBP carboxylase.
abstract: Preincubation of 35S-methionine-labeled chloroplast extracts with ATP at 0 degree C potentiates the subsequent assembly of labeled large subunits into RuBPCase . This is correlated with the dissociation of newly synthesized large subunits from the 29S large subunit binding protein complex. These released large subunits then assemble into RuBPCase in a second, nucleotide-stimulated reaction. The data demonstrate that the 29S complex can play an active role in the assembly of RuBPCase .
