Abstract

Plastid genes are transcribed by DNA-dependent RNA polymerase(s), which have been incompletely characterized and have been examined in a limited number of species. Plastid genomes contain rpoA, rpoB, rpoC1, and rpoC2 coding for alpha, beta, beta', and beta" RNA polymerase subunits that are homologous to the alpha, beta, and beta' subunits that constitute the core moiety of RNA polymerase in bacteria. However, genes with homology to sigma subunits in bacteria have not been found in plastid genomes. An antibody directed against the principal sigma subunit of RNA polymerase from the cyanobacterium Anabaena sp. PCC 7120 was used to probe western blots of purified chloroplast RNA polymerase from maize, rice, Chlamydomonas reinhardtii, and Cyanidium caldarium. Chloroplast RNA polymerase from maize and rice contained an immunoreactive 64-kD protein. Chloroplast RNA polymerase from C. reinhardtii contained immunoreactive 100- and 82-kD proteins, and chloroplast RNA polymerase from C. caldarium contained an immunoreactive 32-kD protein. The elution profile of enzyme activity of both algal chloroplast RNA polymerases coeluted from DEAE with the respective immunoreactive proteins, indicating that they are components of the enzyme. These results provide immunological evidence for sigma-like factors in chloroplast RNA polymerase in higher plants and algae.

摘要

质体基因由依赖DNA的RNA聚合酶转录，这些酶的特性尚未完全明确，且仅在少数物种中进行过研究。质体基因组包含编码α、β、β'和β'' RNA聚合酶亚基的rpoA、rpoB、rpoC1和rpoC2，它们与构成细菌RNA聚合酶核心部分的α、β和β'亚基同源。然而，在质体基因组中尚未发现与细菌中σ亚基同源的基因。一种针对蓝藻鱼腥藻PCC 7120 RNA聚合酶主要σ亚基的抗体，被用于探测来自玉米、水稻、莱茵衣藻和嗜热栖热放线菌的纯化叶绿体RNA聚合酶的蛋白质免疫印迹。玉米和水稻的叶绿体RNA聚合酶含有一种免疫反应性的64-kD蛋白。莱茵衣藻的叶绿体RNA聚合酶含有免疫反应性的100-kD和82-kD蛋白，嗜热栖热放线菌的叶绿体RNA聚合酶含有免疫反应性的32-kD蛋白。两种藻类叶绿体RNA聚合酶的酶活性洗脱图谱与各自的免疫反应性蛋白从DEAE上共同洗脱，表明它们是该酶的组成部分。这些结果为高等植物和藻类叶绿体RNA聚合酶中类似σ因子提供了免疫学证据。
