haemolysin expression modulating protein[2][3] Modulates hemolysin expression, in complex with H-NS; stimulates transposition events; induced by AI-2 pheromone; promotes conjugation and conjugation-induced biofilms[4] Hha is a small transcriptional regulator (8 kDa) that is induced in biofilms[5] and that influences biofilm formation[6]; Hha overexpression reduces biofilm formation by increasing biofilm dispersal[7]. Rather than binding to specific DNA sequences, Hha exhibits non-specific DNA binding. Hha binds in vivo to 15 genes or intergenic regions of CP4-57 and DLP12 including regions close to the prophage attachment (att) sites and that Hha activates the prophage lytic genes alpA, rzpD, appY and yfjZ, as well as induces plaque formation and decreases cell viability[7]. |

Notes
Hha and Cnu are paralogs. The expression of the hly operon of plasmid pHly152 is modulatedby Hha/HN-S. Overexpression of Cnu(YdgT) partially suppresses the hha defect on hylA expression. Hha positively modulates H-NS expression. Induced during biofilm formation.[4]
