Abstract	The amino acid sequence of the RNA polymerase (RNAP) α-subunit is well conserved throughout the Eubacteria. Its C-terminal domain (α-CTD) is important for the transcriptional regulation of specific promoters in both Escherichia coli and Bacillus subtilis, through interactions with transcription factors and/or a DNA element called the “UP element”. However, there is only limited information regarding the α-CTD regulated genes in B. subtilis and the importance of this subunit in the transcriptional regulation of B. subtilis. Here, we established strains and the growth conditions in which the α-subunit of RNAP was replaced with a C-terminally truncated version. Transcriptomic and ChAP-chip analyses revealed that α-CTD deficiency reduced the transcription and RNAP binding of genes related to the utilization of secondary carbon sources, transition state responses, and ribosome synthesis. In E. coli, it is known that α-CTD also contributes to the expression of genes related to the utilization of secondary carbon sources and ribosome synthesis. Our results suggest that the biological importance of α-CTD is conserved in B. subtilis and E. coli, but that its specific roles have diversified between these two bacteria.
