Abstract

Synechocystis sp PCC 6803 Slr1471p, an Oxa1p/Alb3/YidC homolog, is an essential protein for cell viability for which functions in thylakoid membrane biogenesis and cell division have been proposed. Using a fusion of green fluorescent protein to the C terminus of Slr1471p, we found that the mutant slr1471-gfp is photochemically inhibited when light intensities increase to 80 micromol x m(-2) x s(-1). We show that photoinhibition correlates with an increased redox potential of the reaction center quinone Q(A)(-) and a decreased redox potential of Q(B)(-). Analysis reveals that membrane integration of the D1 precursor protein is affected, leading to the accumulation of pD1 in the membrane phase. We show that Slr1471p interacts directly with the D1 protein and discuss why the accumulation of pD1 in two reaction center assembly intermediates is dependent on Slr1471p.

摘要

集胞藻PCC 6803的Slr1471p是一种Oxa1p/Alb3/YidC同源物,是细胞生存能力所必需的蛋白质,有人提出它在类囊体膜生物发生和细胞分裂中发挥作用。通过将绿色荧光蛋白融合到Slr1471p的C末端,我们发现当光强增加到80微摩尔·米-2·秒-1时,突变体slr1471-gfp受到光化学抑制。我们表明,光抑制与反应中心醌Q(A)(-)的氧化还原电位增加和Q(B)(-)的氧化还原电位降低相关。分析表明,D1前体蛋白的膜整合受到影响,导致pD1在膜相中积累。我们表明,Slr1471p与D1蛋白直接相互作用,并讨论了为什么pD1在两个反应中心组装中间体中的积累依赖于Slr1471p。
