The core enzyme has four protein subunits, a dimer of two α proteins, a β protein, and a related β’ subunit. The β and β’ subunits form the catalytic site, and the α subunit helps recognize the promoter. The 3D structure of RNA polymerase shows a deep groove that can hold the template DNA, and a minor groove to hold the growing RNA. Genes have a transcriptional promoter, where RNA polymerase attaches to the DNA and begins making an RNA copy of the template strand. The RNA has three regions: The 5′ UTR contains information important for making the protein, the ORF has the actual coding region translated into amino acids during translation, and the 3′ UTR contains other important regulatory elements.
Finally comes the termination sequence where transcription stops. Bacterial RNA polymerase is made of different protein subunits. The sigma subunit recognizes the –10 and –35 regions and the core enzyme catalyzes the RNA synthesis. RNA polymerase only synthesizes nucleotide additions in a 5′ to 3′ direction. The core enzyme has four protein subunits, a dimer of two α proteins, a β protein, and a related β’ subunit. The β and β’ subunits form the catalytic site, and the α subunit helps recognize the promoter.
