Lpg0393 consists of two domains both of which composed of alpha- helices. The N-terminal domain contains seven helices and makes roughly a 90-degree angle with the C-terminal domain that forms a helical bundle structure [1]. The N-terminal domain is similar to Vps9 domain of Rabex-5. Lpg0393 exhibits a GEF activity toward Rab5, Rab21 and Rab22, and this activity is associated with a VPS9-like domain of the protein.

Lpg0393 is a Legionella pneumophila effector protein. Structure analysis reveals that it has two domains, the N-terminal domain is a Vps9-like domain, which is structurally most similar to the catalytic core of human Rabex-5 that activates the endosomal Rab proteins Rab5, Rab21 and Rab22. The C-terminal domain is a helical bundle domain. The C-terminal helical bundle of Lpg0393 corresponds to the N-terminal helical bundle of Rabex-5, it lacks an obvious region that corresponds to the membrane-binding motif of Rabex-5. One possibility may be that Lpg0393 localization to endosomes depends on an unknown Legionella effector [1].
