YmoA and Hha are highly similar bacterial proteins downregulating gene expression In
Yersinia entero‐colitlca and Escherichia coli. respectively. The pheno‐type of ymoA mutants …

The Hha protein from Escherichia coli is highly similar (82%) to the YmoA protein from
Yersinia enterocolitica. Both are members of a new class of proteins that modulates gene …

In enteric bacteria, proteins of the Hha/YmoA family play a role in the regulation of gene
expression in response to environmental factors. Interaction of both Hha and YmoA with H …

Summary The Hha/YmoA family of proteins is a group of conserved, low‐molecular‐weight
proteins involved in the regulation of gene expression. Studies performed in Escherichia …

MATERIALS AND METHODS Bacterial and phage strains. All strains are derivatives of E.
coli K-12. Strain K37 galK-str r has been described (Miller and Friedman 1980). K5157 is …

The hha gene of Escherichia coli was identified as modulating the expression of the
haemolysin (hly) genes encoded by the recombinant plasmid pANN202‐312. hha mutants …

Abstract Proteins of the Hha/YmoA family co-regulate with H-NS the expression of
horizontally acquired genes in Enterobacteria. Systematic mutations of conserved acidic …

Escherichia coli HU protein is a major component of the bacterial nucleoid. HU stabilizes
higher order nucleoprotein complexes and belongs to a family of DNA architectural proteins …

ABSTRACT The Hha/YmoA family of nucleoid-associated proteins is involved in gene
regulation in enterobacteria. In Salmonella enterica serovar Typhimurium, virulence genes …

We used an expression vector plasmid containing the Escherichia coli K-12 histidine operon
regulatory region to subclone the E. coli hisC gene. Analysis of plasmid-coded proteins …
