Function

[SIDD_LEGPH] Virulence effector that plays a role in hijacking the host vesicular trafficking by recruiting the small guanosine triphosphatase (GTPase) Rab1 to the cytosolic face of the Legionella-containing vacuole (LCVs). Acts as an adenosine monophosphate-protein hydrolase (de-AMPylase) by mediating the hydrolysis of adenosine 5'-monophosphate (AMP) to 'Tyr-77' of host RAB1B, thereby releasing RAB1B from bacterial phagosomes and rendering RAB1B accessible for inactivation by LepB. De-AMPylation of RAB1B cannot take place when LidA is bound to RAB1B.[1] [2] [3]

About this Structure

4iip is a 1 chain structure with sequence from Legionella pneumophila subsp. pneumophila str. philadelphia 1. Full crystallographic information is available from OCA.
