The glutamic acid residue at amino acid 261 of the alpha subunit is a determinant of the intrinsic efficiency of RNA polymerase at the metE core promoter in Escherichia coli.
A mutation in the rpoA gene (which encodes the alpha subunit of RNA polymerase) that changed the glutamic acid codon at position 261 to a lysine codon decreased the level of expression of a metE-lacZ fusion 10-fold; this decrease was independent of the MetR-mediated activation of metE-lacZ.
