Abstract

We localized five rpoC (β') mutations affecting Escherichia coli RNA polymerase assembly. The Ts4, XH56, and R120 mutations changed β' residues conserved throughout eubacteria; the JE10092 mutation occurred in the hypervariable region; rpoC1 (TsX) changed a universally conserved residue and corresponds to yeast rpbl-1. Thus, distinct, predominantly conserved β' residues participate in interactions holding RNA polymerase together.
