Abstract

RNA polymerase was purified from the unicellular cyanobacterium, Synechococcus sp. strain PCC 7942, and found to be associated with a 52 kilodalton (kDa) polypeptide. The determined N-terminal sequence of the polypeptide was identical to the predicted amino-acid sequence of the rpoD1 gene product. Furthermore, the rpoD1 gene is suggested to be indispensable for viability by the inability to disrupt the gene. These results indicate that the rpoD1 gene product is the principal sigma factor of RNA polymerase.
