	Abstract

We show in this report that chromosomal hha-like genes are restricted to the Enterobacteriaceae. The H-NS N-terminal domain of members of this family includes an unaltered seven-aminoacid sequence, located between helixes 1 and 2, termed Hha signature that contains key residues for H-NS-Hha interaction.
