Legionella pneumophila infects alveolar macrophages and can cause life-threatening pneumonia in humans. Upon internalization into the host cell, L. pneumophila injects numerous effector proteins into the host cytoplasm as a part of its pathogenesis. LegK7 is an effector kinase of L. pneumophila that functionally mimics the eukaryotic Mst kinase and phosphorylates the host MOB1 protein to exploit the Hippo pathway. To elucidate the LegK7 activation mechanism, we determined the apo structure of LegK7 in an inactive form and performed a comparative analysis of LegK7 structures. LegK7 is a non-RD kinase that contains an activation segment that is ordered, irrespective of stimulation, through a unique beta-hairpin-containing segment, and it does not require phosphorylation of the activation segment for activation. Instead, bacterial LegK7 becomes an active kinase via its heterologous molecular interaction with the host MOB1 protein. MOB1 binding triggers reorientation of the two lobes of the kinase domain, as well as a structural change in the interlobe hinge region in LegK7, consequently reshaping the LegK7 structure into an ATP binding-compatible closed conformation. Furthermore, we reveal that LegK7 is an atypical kinase that contains an N-terminal capping domain and a hydrophilic interlobe linker motif, which play key roles in the MOB1-induced activation of LegK7.
