摘要

Legionella pneumophila dot mutations cause defects in intracellular targeting of the microorganism within cultured macrophages. Each of the previously characterized dot mutations was shown to be complemented by a single open reading frame designated dotA. The defects caused by the mutations appear to be due to disrupted function of the predicted 1048-amino-acid residue DotA protein, and not by polarity effects on a downstream gene. Complementation studies indicated that the product of the dotA53 mutation results in a partially functional DotA protein, consistent with a stable N-terminal fragment having biological activity.
