#Unit 3. Fundamental Processes

The carboxy-terminal domain of the a subunit (aCTD) recognizes the Up-element (where present), whereas s regions 2 and 4 recognize the –10 and –35 regions

#Unit 3. Fundamental Processes

This consensus sequence was derived by aligning 300 sequences known to function as s70 promoters and ascertaining the most common base found at each position in the –35 and –10 hexamers.
