This subdomain is found in the Rab1 GTPase-activating protein (GAP) domain of GAP LepB present in Legionella pneumophilia. LepB inactivates Rab1, a key regulator of the secretory vesicular trafficking machinery, by acting as a GTPase-activating protein. LepB is also an antagonist of DrrA, which promotes Rab1. LepB acts by an atypical RabGAP mechanism that is reminiscent of classical GAPs. This is the C-terminal subdomain of the GAP domain and consists of an unusual fold [1].	Domain

This is a subdomain of a Rab GTPase-activating protein (GAP) effector from Legionella pneumophilia. This GAP modulates Rab enzymes that act as molecular switches in regulating vesicular transport in eukaryotic cells. This N-terminal subdomain belongs to the the GAP domain of the protein. The catalytic arginine finger (Arg444) is located within this sub-domain and it is the only arginine residue required for GAP activity [1].	Domain
