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 .
在0摄氏度下,将35S-甲硫氨酸标记的叶绿体提取物与ATP预温育,可增强随后标记的大亚基组装成核酮糖-1,5-二磷酸羧化酶(RuBPCase)的能力。这与新合成的大亚基从29S大亚基结合蛋白复合物上解离有关。这些释放出来的大亚基随后在第二个由核苷酸刺激的反应中组装成RuBPCase。数据表明,29S复合物在RuBPCase的组装过程中可发挥积极作用。
