| Abstract |
Biodegradative arginine decarboxylase is inducible by acid and is derepressed in an hns mutant. Several plasmids from an Escherichia coli library that could complement the hns phenotype were characterized and placed into groups. One group includes plasmids that contain the hns gene and are considered true complements. Another group was found to carry the hfq gene, which encodes the host factor HF-1 for bacteriophage Q beta replication. Plasmids of the third group contain inserts that mapped at 60.2 min on the E. coli chromosome. We identified an open reading frame (stpA) with a deduced amino acid sequence showing more than 60% identity with the sequences of H-NS proteins from several species as being responsible for the hns complementing phenotype of the third group. |
