光合作用装置的主要类囊体蛋白复合体的生物发生需要辅助蛋白来支持单独的组装步骤。在这里,我们鉴定了一个植物谱系特异性基因CGL160,它的同源基因ATP1在许多蓝藻中以操纵子样的排列与ATP合成酶亚基共出现。拟南芥T-DNA插入突变体不再积累核编码的CGL160蛋白,积累的叶绿体ATP合成酶水平不到野生型的25%。在短日照或波动光生长条件下,分别表现出严重的表型或生长表型,但在长日照恒定生长条件下,这种情况有所改善,因为长日光生长条件对突变体的生长、ATP合成酶活性和光合作用电子传递影响较小。在cgl160突变体中,其他光合作用复合体的积累基本上没有受到影响,这表明CGL160是CF1CF0复合体的特异性组装或稳定因子。CGL160不存在于成熟的组装复合体中,但它确实与ATP合成酶的亚单位特异地相互作用,主要是与外源性CF1亚复合体中的那些亚单位相互作用。因此,我们认为它可能有助于CF1组装到全息复合体中。
The biogenesis of the major thylakoid protein complexes of the photosynthetic apparatus requires auxiliary proteins supporting individual assembly steps. Here, we identify a plant lineage specific gene, CGL160, whose homolog, atp1, co-occurs with ATP synthase subunits in an operon-like arrangement in many cyanobacteria. Arabidopsis thaliana T-DNA insertion mutants, which no longer accumulate the nucleus-encoded CGL160 protein, accumulate less than 25% of wild-type levels of the chloroplast ATP synthase. Severe cosmetic or growth phenotypes result under either short day or fluctuating light growth conditions, respectively, but this is ameliorated under long day constant light growth conditions where the growth, ATP synthase activity and photosynthetic electron transport of the mutants are less affected. Accumulation of other photosynthetic complexes is largely unaffected in cgl160 mutants, suggesting that CGL160 is a specific assembly or stability factor for the CF1CF0 complex. CGL160 is not found in the mature assembled complex but it does interact specifically with subunits of ATP synthase, predominantly those in the extrinsic CF1 sub-complex. We suggest therefore that it may facilitate the assembly of CF1 into the holocomplex.
