Background: Pulmonary Francisella infection resulted in reduction of plasma alkaline phosphatase activity. Results: Francisella heat shock protein DnaK binds to alkaline phosphatase thus reducing enzymatic activity. Conclusion: A Francisella protein component responsible for alkaline phosphatase inhibition was identified. Significance: We present a novel mechanism used by a bacterial pathogen to evade the host's defense.
