Haemophilus influenzae utilizes hemoglobin and hemoglobin-haptoglobin as heme sources. The H. influenzae hemoglobin- and hemoglobin-haptoglobin binding protein genes, hgpA, hgpB, and hgpC, contain lengths of tetrameric CCAA repeats. Using an hgpA-lacZ translational gene fusion, we demonstrate phase-variable expression of lacZ associated with alteration in the length of the CCAA repeat region.
