The content of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) in the photosynthetic purple sulfur bacterium, Chromatium vinosum, grown either heterotrophically or autotrophically, was highly correlated with the level of 2.0-kb mRNA encoding genes for both large (rbcL) and small (rbcS) subunits. This result indicates the transcriptional regulation of Rubisco biosynthesis in Chromatium cells. In the analysis of transcripts for rbcL and rbcS in Escherichia coli transformed by a plasmid bearing both genes downstream of E. coli tac promoter (pCKS1), the mRNAs were found to be the same sizes as those from Chromatium. However, we were unable to detect mRNA for Rubisco in E. coli harboring a plasmid containing the genes for Rubisco and its own promoter without any E. coli promoters (pCUB1). In the in vitro transcription experiment of pCKS1 and pCUB1 by E. coli RNA polymerase, it was observed that the enzyme could not recognize the Rubisco promoter. Therefore, we have purified RNA polymerase from Chromatium cells and developed a homologous in vitro transcription system. We have detected factor(s) for transcriptional regulation from either heterotrophically or autotrophically grown cells of Chromatium using the homologous in vitro transcription system.
