CC -!- FUNCTION: Virulence effector that plays a role in hijacking the host
CC vesicular trafficking by recruiting the small guanosine triphosphatase
CC (GTPase) Rab1 to the cytosolic face of the Legionella-containing
CC vacuole (LCVs). Acts as a phosphocholine hydrolase by mediating the
CC hydrolysis of phosphocholine to Ser residues of host RAB1 (RAB1A, RAB1B
CC or RAB1C). Dephosphocholination of target proteins restores
CC accessibility to GTPase effector LepB. Can act on both GDP-bound and
CC GTP-bound Rab proteins. {ECO:0000269|PubMed:22158903,
CC ECO:0000269|PubMed:22307087, ECO:0000269|PubMed:22411835}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[Rab1 protein]-O-phosphocholine-L-serine + H2O = [Rab1
CC protein]-L-serine + H(+) + phosphocholine; Xref=Rhea:RHEA:56084,

CC ChEBI:CHEBI:295975; Evidence={ECO:0000269|PubMed:22158903};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=65.5 uM for GDP-bound RAB1B {ECO:0000269|PubMed:22307087};
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:22158903}. Host
CC cytoplasm {ECO:0000269|PubMed:22158903}. Note=Translocated into the
CC host cell via the type IV secretion system (T4SS).
