Summary

Recombinant DNA techniques allow rapid construction and characterization of tools for genetic dissection of essential genes. In this report, we describe construction of a set of deletions in rpoD, the gene which encodes the sigma subunit of E. coli RNA polymerase. We used this deletion set to identify a region of the sigma polypeptide which is dispensable for its function.
