Sinorhizobium meliloti, a gram-negative soil bacterium, forms a nitrogen-fixing symbiotic relationship with members of the legume family. To facilitate our studies of transcription in S. meliloti, we cloned and characterized the gene for the alpha subunit of RNA polymerase (RNAP). S. meliloti rpoA encodes a 336-amino-acid, 37-kDa protein.
